1. Introduction
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. 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) [RFC2622] inetnum: class [INETNUM] to
refer to geofeed data, and how to prudently use them. In all places
inetnum: is used, inet6num: should also be assumed [INET6NUM].
An optional, but utterly awesome, means for authenticating geofeed
data is also defined.
1.1. Requirements Language
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.

2. Geofeed Files
Geofeed files are described in [RFC8805]. They provide a facility
for an IP address resource 'owner' to associate those IP addresses to
geographic locale(s).
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
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, as may be likely if the location data are maintained by a
different department than address management, dual IPv4/IPv6 spaces
are represented, etc.
This document also suggests optional data for geofeed files to
provide stronger authenticity to the data.
3. inetnum: Class
RPSL, [RFC2622], as used by the Regional Internet Registries (RIRs),
has been augmented with the inetnum: [INETNUM] and the inet6num:
[INET6NUM] classes; each of which describes an IP address range and
its attributes.
Ideally, RPSL would be augmented to define a new RPSL geofeed:
attribute in the inetnum: class. Until such time, this document
defines the syntax of a Geofeed remarks: attribute which contains an
HTTPS URL of a geofeed file. The format MUST be as in this example,
"remarks: Geofeed " followed by a URL which will vary.
inetnum: 192.0.2.0/24 # example
remarks: Geofeed https://example.com/geofeed.csv
Any particular inetnum: object MAY have, at most, one geofeed
reference, whether a remark: or a proper geofeed: attribute when one
is defined.
inetnum: objects form a hierarchy, see [INETNUM] Section 4.2.4.1,
Hierarchy of INETNUM Objects. Geofeed references SHOULD be at the
lowest applicable inetnum: object. When fetching, the most specific
inetnum: object with a geofeed reference MUST be used.
When geofeed references are provided by multiple inetnum: objects
which have identical address ranges, then the geofeed reference on
Candela, et al. Expires April 15, 2021 [Page 3]
Internet-Draft Finding Geofeeds October 2020
the inetnum: with the most recent last-modified: attribute SHOULD be
preferred.
It is significant that geofeed data may have finer granularity than
the inetnum: which refers to them.
Currently, the registry data published by ARIN is not the same RPSL
as the other registries; therefore, when fetching from ARIN via FTP
[RFC0959], whois [RFC3912], RDAP [RFC7482], or whatever, the
"NetRange" attribute/key must be treated as "inetnum" and the
"Comment" attribute must be treated as "remarks".
4. Authenticating Geofeed Data
The question arises of whether a particular geofeed data set is
valid, i.e. authorized by the 'owner' of the IP address space and is
authoritative in some sense. The inetnum: which points to the
geofeed file provides some assurance. Unfortunately the RPSL in many
repositories is weakly authenticated at best. An approach where RPSL
was signed a la [RFC7909] would be good, except it would have to be
deployed by all RPSL registries.
An optional authenticator MAY be appended to a geofeed file. It
would be essentially a digest of the main body of the file signed by
the private key of the relevant RPKI certificate for the covering
address range. One needs a format that bundles the relevant RPKI
certificate with the signature and the digest of the geofeed text.
Borrowing detached signatures from [RFC5485], after text file
canonicalization (Sec 2.2), the Cryptographic Message Syntax (CMS)
[RFC3852] would be used to create a detached DER encoded signature
which is then BASE64 encoded and line wrapped to 72 or fewer
characters.
Both the address ranges of the signing certificate and of the
inetnum: MUST cover all prefixes in the geofeed file; and the address
range of the signing certificate must cover that of the inetnum:.
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 CIDR prefix
boundaries, while those of geofeed lines must.
As the signer would need to specify the covered RPKI resources
relevant to the signature, the RPKI certificate covering the inetnum:
object's address range would be included in the [RFC3852] CMS
SignedData certificates field.
Candela, et al. Expires April 15, 2021 [Page 4]
Internet-Draft Finding Geofeeds October 2020
Identifying the private key associated with the certificate, and
getting the department with the 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.
Until [RFC8805] is updated to formally define such an appendix, it
MUST be 'hidden' as a series of "#" comments at the end of the
geofeed file. This is a cryptographically incorrect, albeit simple
example. A correct and full example is in Appendix A.

# End Signature: 192.0.2.0/24
5. Operational Considerations
To create the needed inetnum: objects, an operator wishing to
register the location of their geofeed file needs to coordinate with
their RIR/NIR and/or any provider LIR which has assigned prefixes to
them. RIRs/NIRs provide means for assignees to create and maintain
inetnum: objects. They also provide means of [sub-]assigning IP
address resources and allowing the assignee to create whois data,
including inetnum: objects, and thereby referring to geofeed files.
The geofeed files SHOULD be published over and fetched using https
[RFC2818].
When using data from a geofeed file, one MUST ignore data outside of
the referring inetnum: object's inetnum: attribute address range.
Iff the geofeed file is not signed per Section 4, then multiple
inetnum: objects MAY refer to the same geofeed file, and the consumer
MUST use only geofeed lines where the prefix is covered by the
address range of the inetnum: object they have followed.
To minimize the load on RIR whois [RFC3912] services, use of the
RIR's FTP [RFC0959] services SHOULD be the preferred access. This
also provides bulk access instead of fetching with a tweezers.
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
Candela, et al. Expires April 15, 2021 [Page 5]
Internet-Draft Finding Geofeeds October 2020
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].
An entity fetching geofeed data using these mechanisms MUST NOT do
frequent real-time look-ups to prevent load on RPSL and geofeed
servers. [RFC8805] Section 3.4 suggests use of the [RFC7234] HTTP
Expires Caching Header to signal when geofeed data should be
refetched. As the data change very infrequently, in the absence of
such an HTTP Header signal, collectors MUST NOT fetch more frequently
than weekly. It would be wise 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.
6. Security Considerations
It would be generally prudent for a consumer of geofeed data to also
use other sources to cross-validate the data. All of the Security
Considerations of [RFC8805] apply here as well.
As mentioned in Section 4, many RPSL repositories have weak if any
authentication. This would allow spoofing of inetnum: objects
pointing to malicious geofeed files. Section 4 suggests an
unfortunately complex method for stronger authentication based on the
RPKI.
If an inetnum: for a wide prefix (e.g. a /16) points to an RPKI-
signed geofeed file, a customer or attacker could publish a unsigned
equal or narrower (e.g. a /24) inetnum: in a whois registry which has
weak authorization.
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.
7. IANA Considerations
IANA is asked to register object identifiers for one content type in
the "SMI Security for S/MIME CMS Content Type
(1.2.840.113549.1.9.16.1)" registry as follows:
