Providers of Internet content and other services may wish to customize those services based on the geographic location of the user of the service. This is often done using the source IP address used to contact the service, which may not point to a user, see [RFC6269], Section 14 in particular. Also, infrastructure and other services might wish to publish the locale of their services. [RFC8805] defines geofeed, a syntax to associate geographic locales with IP addresses, but it does not specify how to find the relevant geofeed data given an IP address.¶
This document specifies how to augment the Routing Policy Specification Language (RPSL) [RFC2725] inetnum: class to refer specifically to geofeed data files and how to prudently use them. In all places inetnum: is used, inet6num: should also be assumed [RFC4012].¶
The reader may find [INETNUM] and [INET6NUM] informative, and certainly more verbose, descriptions of the inetnum: database classes.¶
An optional utterly awesome but slightly complex means for authenticating geofeed data is also defined in Section 5.¶
This document obsoletes [RFC9092]. Changes from [RFC9092] include the following:¶
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all capitals, as shown here.¶
Geofeed files are described in [RFC8805]. They provide a facility for an IP address resource "owner" to associate those IP addresses to geographic locales.¶
Per [RFC8805], geofeed files consist of CSVs (Comma Separated Values) in UTF-8 text format; not HTML, richtext, or other formats.¶
Content providers and other parties who wish to locate an IP address to a geographic locale need to find the relevant geofeed data. In Section 3, this document specifies how to find the relevant geofeed [RFC8805] file given an IP address.¶
Geofeed data for large providers with significant horizontal scale and high granularity can be quite large. The size of a file can be even larger if an unsigned geofeed file combines data for many prefixes, if dual IPv4/IPv6 spaces are represented, etc.¶
Geofeed data do have privacy considerations (see Section 7); this process makes bulk access to those data easier.¶
This document also suggests an optional signature to strongly authenticate the data in the geofeed files.¶
The original RPSL specifications starting with [RIPE81], [RIPE181], and a trail of subsequent documents were written by the RIPE community. The IETF standardized RPSL in [RFC2622] and [RFC4012]. Since then, it has been modified and extensively enhanced in the Regional Internet Registry (RIR) community, mostly by RIPE [RIPE-DB]. Currently, change control effectively lies in the operator community.¶
The RPSL, and [RFC2725] and [RFC4012] used by the Regional Internet Registries (RIRs), specify the inetnum: database class. Each of these objects describes an IP address range and its attributes. The inetnum: objects form a hierarchy ordered on the address space.¶
Ideally, RPSL would be augmented to define a new RPSL geofeed: attribute in the inetnum: class. Absent implementation of the geofeed: attribute in a particular RIR database, this document defines the syntax of a Geofeed remarks: attribute, which contains an HTTPS URL of a geofeed file. The format of the inetnum: geofeed remarks: attribute MUST be as in this example, "remarks: Geofeed ", where the token "Geofeed " MUST be case sensitive, followed by a URL that will vary, but it MUST refer only to a single geofeed [RFC8805] file.¶
inetnum: 192.0.2.0/24 # example
remarks: Geofeed https://example.com/geofeed
¶
While we leave global agreement of RPSL modification to the relevant parties, we specify that a proper geofeed: attribute in the inetnum: class MUST be "geofeed:" and MUST be followed by a single URL that will vary, but it MUST refer only to a single geofeed [RFC8805] file.¶
inetnum: 192.0.2.0/24 # example
geofeed: https://example.com/geofeed
¶
The URL uses HTTPS, so the WebPKI provides authentication, integrity, and confidentiality for the fetched geofeed file. However, the WebPKI can not provide authentication of IP address space assignment. In contrast, the RPKI (see [RFC6481]) can be used to authenticate IP space assignment; see optional authentication in Section 5.¶
Until all producers of inetnum: objects, i.e., the RIRs, state that they have migrated to supporting a geofeed: attribute, consumers looking at inetnum: objects to find geofeed URLs MUST be able to consume both the remarks: and geofeed: forms.¶
The migration not only implies that the RIRs support the geofeed: attribute, but that all registrants have migrated any inetnum: objects from remarks: to geofeed: attributes.¶
Any particular inetnum: object SHOULD have, at most, one geofeed reference, whether a remarks: or a proper geofeed: attribute when it is implemented. If there is more than one, the geofeed: attribute SHOULD be used.¶
For inetnum:s covering the same address range, or an inetnum: with both remarks: and geofeed: attributes, a signed geofeed file SHOULD be preferred over an unsigned file.¶
If a geofeed file describes multiple disjoint ranges of IP address space, there are likely to be geofeed references from multiple inetnum: objects. Files with geofeed references from multiple inetnum: objects are not compatible with the signing procedure in Section 5.¶
An unsigned, and only an unsigned, geofeed file MAY be referenced by multiple inetnum:s and MAY contain prefixes from more than one registry.¶
When geofeed references are provided by multiple inetnum: objects that have identical address ranges, then the geofeed reference on the inetnum: with the most recent last-modified: attribute SHOULD be preferred.¶
As inetnum: objects form a hierarchy, geofeed references SHOULD be at the lowest applicable inetnum: object covering the relevant address ranges in the referenced geofeed file. When fetching, the most specific inetnum: object with a geofeed reference MUST be used.¶
It is significant that geofeed data may have finer granularity than the inetnum: that refers to them. For example, an INETNUM object for an address range P could refer to a geofeed file in which P has been subdivided into one or more longer prefixes.¶
This document is to provides a guideline for how interested parties should fetch and read geofeed files.¶
Historically, before [RFC9092], this was done in varied ways, at the discretion of the implementer, often without consistent authentication, where data were mostly imported from email without formal authorisation or validation.¶
To minimize the load on RIRs' WHOIS [RFC3912] services, the RIR's FTP [RFC0959] services SHOULD be used for large-scale access to gather inetnum:s with geofeed references. This uses efficient bulk access instead of fetching via brute-force search through the IP space.¶
When an inetnum: with a geofeed file reference is identified, the file MUST be downloaded using HTTPS.¶
When reading data from the geofeed file, one MUST ignore data outside the referring inetnum: object's address range. This is to avoid importing data about ranges not under the control of the operator. If geofeed files are fetched, other location information from the inetnum: MUST be ignored.¶
Given an address range of interest, the most specific inetnum: object with a geofeed reference MUST be used to fetch the geofeed file. For example, if the fetching party finds the following inetnum: objects:¶
inetnum: 192.0.2.0/12 # example
remarks: Geofeed https://example.com/geofeed_1
inetnum: 192.0.2.0/24 # example
remarks: Geofeed https://example.com/geofeed_2
¶
and the file geofeed_1 contains geolocation data about 192.0.2.0/29, this MUST be discarded because 192.0.2.0/24 is within the more specific inetnum: covering the address range and that inetnum: has a geofeed reference.¶
If an inetnum: object has both remarks: with geofeed data and also has a geofeed: attribute, the geofeed: attribute SHOULD be used and the remarks: ignored.¶
Hints in inetnum:s such as country:, geoloc:, etc. tend to be administrative, and not deployment specific. Consider large, possibly global, providers with headquarters very far from most of their deployments. Therefore, if geofeed data are specified, either as a geofeed: attribute or in a geofeed remarks: attribute, other geographic hints such as country:, geoloc:, DNS geoloc RRsets, etc., for that address range MUST be ignored.¶
There is open-source code to traverse the RPSL data across all of the RIRs, collect all geofeed references, and process them [GEOFEED-FINDER]. It implements the steps above and of all the Operational Considerations described in Section 6, including caching. It produces a single geofeed file, merging all the geofeed files found. This open-source code can be run daily by a cronjob, and the output file can be directly used.¶
The question arises whether a particular geofeed [RFC8805] data set is valid, i.e., is authorized by the "owner" of the IP address space and is authoritative in some sense. The inetnum: that points to the geofeed [RFC8805] file provides some assurance. Unfortunately, the RPSL in some repositories is weakly authenticated at best. An approach where RPSL was signed per [RFC7909] would be good, except it would have to be deployed by all RPSL registries, and there is a fair number of them.¶
The remainder of this section specifies an optional authenticator for the geofeed data set that follows the Signed Object Template for the Resource Public Key Infrastructure (RPKI) [RFC6488].¶
A single optional authenticator MAY be appended to a geofeed [RFC8805] file. It is a digest of the main body of the file signed by the private key of the relevant RPKI certificate for a covering address range. The following format bundles the relevant RPKI certificate with a signature over the geofeed text.¶
The canonicalization procedure converts the data from their internal character representation to the UTF-8 [RFC3629] character encoding, and the <CRLF> sequence MUST be used to denote the end of each line of text. A blank line is represented solely by the <CRLF> sequence. For robustness, any non-printable characters MUST NOT be changed by canonicalization. Trailing blank lines MUST NOT appear at the end of the file. That is, the file must not end with multiple consecutive <CRLF> sequences. Any end-of-file marker used by an operating system is not considered to be part of the file content. When present, such end-of-file markers MUST NOT be covered by the digital signature.¶
If the authenticator is not in the canonical form described above, then, the authenticator is invalid.¶
Borrowing detached signatures from [RFC5485], after file canonicalization, the Cryptographic Message Syntax (CMS) [RFC5652] is used to create a detached DER-encoded signature that is then Base64 encoded with padding (as defined in Section 4 of [RFC4648]) and line wrapped to 72 or fewer characters. The same digest algorithm MUST be used for calculating the message digest of the content being signed, which is the geofeed file, and for calculating the message digest on the SignerInfo SignedAttributes [RFC8933]. The message digest algorithm identifier MUST appear in both the CMS SignedData DigestAlgorithmIdentifiers and the SignerInfo DigestAlgorithmIdentifier [RFC5652]. The RPKI certificate covering the geofeed inetnum: object's address range is included in the CMS SignedData certificates field [RFC5652].¶
The address range of the signing certificate MUST cover all prefixes in the signed geofeed file. The signing certificate MUST NOT include the Autonomous System Identifier Delegation certificate extension [RFC3779].¶
As with many other RPKI signed objects, the IP Address Delegation certificate extension MUST NOT use the "inherit" capability defined in Section 2.2.3.5 of [RFC3779]. An IP Address Delegation extension using "inherit" would complicate processing. The implementation would have to build the certification path from the end-entity to the trust anchor, then validate the path from the trust anchor to the end-entity, and then the parameter would have to be remembered when the validated public key was used to validate a signature on a CMS object. Having to remember things from certification path validation for use with CMS object processing is too hard. And, the certificates do not get that much bigger by repeating the information.¶
An address range A "covers" address range B if the range of B is identical to or a subset of A. "Address range" is used here because inetnum: objects and RPKI certificates need not align on Classless Inter-Domain Routing (CIDR) [RFC4632] prefix boundaries, while those of the lines in a geofeed file do align.¶
The CA SHOULD sign only one geofeed file with each generated private key and SHOULD generate a new key pair for each new version of a perticular geofeed file. The CA MUST generate a new EE certificate for each signing of a particular geofeed file. An associated EE certificate used in this fashion is termed a "one-time-use" EE certificate (see Section 3 of [RFC6487]).¶
Identifying the private key associated with the certificate and getting the department that controls the private key (which might be stored in a Hardware Security Module (HSM)) to generate the CMS signature is left as an exercise for the implementor. On the other hand, verifying the signature has no similar complexity; the certificate, which is validated in the public RPKI, contains the needed public key. The RPKI trust anchors for the RIRs are expected to already be available to the party performing signature validation. Validation of the CMS signature over the geofeed file involves:¶
All of the above steps MUST be successful to consider the geofeed file signature as valid.¶
Identifying the private key associated with the certificate and getting the department with the Hardware Security Module (HSM) to sign the CMS blob is left as an exercise for the implementor. On the other hand, verifying the signature requires no complexity; the certificate, which can be validated in the public RPKI, has the needed public key.¶
The authenticator MUST be hidden as a series of "#" comments at the end of the geofeed file. The following simple example is cryptographically incorrect:¶
# RPKI Signature: 192.0.2.0 - 192.0.2.255
# MIIGlwYJKoZIhvcNAQcCoIIGiDCCBoQCAQMxDTALBglghkgBZQMEAgEwDQYLKoZ
# IhvcNAQkQAS+gggSxMIIErTCCA5WgAwIBAgIUJ605QIPX8rW5m4Zwx3WyuW7hZu
...
# imwYkXpiMxw44EZqDjl36MiWsRDLdgoijBBcGbibwyAfGeR46k5raZCGvxG+4xa
# O8PDTxTfIYwAnBjRBKAqAZ7yX5xHfm58jUXsZJ7Ileq1S7G6Kk=
# End Signature: 192.0.2.0 - 192.0.2.255
¶
A correct and full example is in Appendix A.¶
The CMS signature does not cover the signature lines.¶
The bracketing "# RPKI Signature:" and "# End Signature:" MUST be present as shown in the example. The RPKI Signature's IP address range MUST match that of the geofeed URL in the inetnum: that points to the geofeed file.¶
To create the needed inetnum: objects, an operator wishing to register the location of their geofeed file needs to coordinate with their Regional Internet Registry (RIR) or National Internet Registry (NIR) and/or any provider Local Internet Registry (LIR) that has assigned address ranges to them. RIRs/NIRs provide means for assignees to create and maintain inetnum: objects. They also provide means of assigning or sub-assigning IP address resources and allowing the assignee to create WHOIS data, including inetnum: objects, thereby referring to geofeed files.¶
The geofeed files MUST be published via and fetched using HTTPS [RFC2818].¶
When using data from a geofeed file, one MUST ignore data outside the referring inetnum: object's inetnum: attribute address range.¶
If and only if the geofeed file is not signed per Section 5, then multiple inetnum: objects MAY refer to the same geofeed file, and the consumer MUST use only lines in the geofeed file where the prefix is covered by the address range of the inetnum: object's URL it has followed.¶
If the geofeed file is signed, and the signer's certificate changes, the signature in the geofeed file MUST be updated.¶
It is good key hygiene to use a given key for only one purpose. To dedicate a signing private key for signing a geofeed file, an RPKI Certification Authority (CA) may issue a subordinate certificate exclusively for the purpose shown in Appendix A.¶
Harvesting and publishing aggregated geofeed data outside of the RPSL model should be avoided as it can have the effect that more specifics from one aggregatee could undesirably affect the less specifics of a different aggregatee. Moreover, publishing aggregated geofeed data prevents the reader of the data to perform the checks described in Section 4 and Section 5.¶
Currently, geolocation providers have bulk WHOIS data access at all the RIRs. An anonymized version of such data is openly available for all RIRs except ARIN, which requires an authorization. However, for users without such authorization, the same result can be achieved with extra RDAP effort. There is open-source code to pass over such data across all RIRs, collect all geofeed references, and process them [GEOFEED-FINDER].¶
To prevent undue load on RPSL and geofeed servers, entity-fetching geofeed data using these mechanisms MUST NOT do frequent real-time lookups. Section 3.4 of [RFC8805] suggests use of the HTTP Expires header [RFC7234] to signal when geofeed data should be refetched. As the data change very infrequently, in the absence of such an HTTP Header signal, collectors SHOULD NOT fetch more frequently than weekly. It would be polite not to fetch at magic times such as midnight UTC, the first of the month, etc., because too many others are likely to do the same.¶
[RFC8805] geofeed data may reveal the approximate location of an IP address, which might in turn reveal the approximate location of an individual user. Unfortunately, [RFC8805] provides no privacy guidance on avoiding or ameliorating possible damage due to this exposure of the user. In publishing pointers to geofeed files as described in this document, the operator should be aware of this exposure in geofeed data and be cautious. All the privacy considerations of Section 4 of [RFC8805] apply to this document.¶
Where [RFC8805] provided the ability to publish location data, this document makes bulk access to those data readily available. This is a goal, not an accident.¶
Currently, the geofeed: attribute in inetnum objects has been implemented in the RIPE and APNIC databases.¶
Registrants in databases which do not yet support the geofeed: attribute are using the remarks:, or equivalent, attribute.¶
Currently, the registry data published by ARIN are not the same RPSL as that of the other registries (see [RFC7485] for a survey of the WHOIS Tower of Babel); therefore, when fetching from ARIN via FTP [RFC0959], WHOIS [RFC3912], the Registration Data Access Protocol (RDAP) [RFC9082], etc., the "NetRange" attribute/key must be treated as "inetnum", and the "Comment" attribute must be treated as "remarks".¶
[rpki-client] can be used to authenticate a signed geofeed file.¶
It is generally prudent for a consumer of geofeed data to also use other sources to cross-validate the data. All the security considerations of [RFC8805] apply here as well.¶
The consumer of geofeed data SHOULD fetch and process the data themselves. Importing datasets produced and/or processed by a third-party places ill-advised trust in the third-party.¶
As mentioned in Section 5, some RPSL repositories have weak, if any, authentication. This allows spoofing of inetnum: objects pointing to malicious geofeed files. Section 5 suggests an unfortunately complex method for stronger authentication based on the RPKI.¶
For example, if an inetnum: for a wide address range (e.g., a /16) points to an RPKI-signed geofeed file, a customer or attacker could publish an unsigned equal or narrower (e.g., a /24) inetnum: in a WHOIS registry that has weak authorization, abusing the rule that the most-specific inetnum: object with a geofeed reference MUST be used.¶
If signatures were mandatory, the above attack would be stymied, but of course that is not happening anytime soon.¶
The RPSL providers have had to throttle fetching from their servers due to too-frequent queries. Usually, they throttle by the querying IP address or block. Similar defenses will likely need to be deployed by geofeed file servers.¶
There are no new actions needed by the IANA.¶
Thanks to Rob Austein for CMS and detached signature clue, George Michaelson for the first and substantial external review, and Erik Kline who was too shy to agree to coauthorship. Additionally, we express our gratitude to early implementors, including Menno Schepers; Flavio Luciani; Eric Dugas; and Kevin Pack. Also, thanks to the following geolocation providers who are consuming geofeeds with this described solution: Jonathan Kosgei (ipdata.co), Ben Dowling (ipinfo.io), and Pol Nisenblat (bigdatacloud.com). For an amazing number of helpful reviews, we thank Job Snijders, who also found an ASN.1 'inherit' issue; Adrian Farrel; Antonio Prado; Francesca Palombini; Jean-Michel Combes (INTDIR); John Scudder; Kyle Rose (SECDIR); Martin Duke; Murray Kucherawy; Paul Kyzivat (GENART); Rob Wilton; Roman Danyliw; and Ties de Kock.¶
This appendix provides an example, including a trust anchor, a CRL signed by the trust anchor, a CA certificate subordinate to the trust anchor, a CRL signed by the CA, an end-entity certificate subordinate to the CA for signing the geofeed, and a detached signature.¶
The trust anchor is represented by a self-signed certificate. As usual in the RPKI, the trust anchor has authority over all IPv4 address blocks, all IPv6 address blocks, and all AS numbers.¶
