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
