For the clients, we can add their resources to our Geofeed, which we public in RIPE Database.Self-published IP Geolocation Data or simply a Goefeed, is an advanced topic. The first thing to mention is that the Geofeed is currently a draft and not an approved RFC. This fact, however, did not stop the internet community from embracing the concept. The first version of the draft was published in 2013, so it has been around for a while.
The Geofeed allows network operators to publish the IP geolocation for the IP blocks that are under their control. The feeds are published in the CSV format and contain the following information:
ip_range,country,region,city,postal_code
The idea is that the content providers will be able to process changes to your IP space geolocation automatically, based on the Geofeed that you publish, which saves you time on having to contact these providers individually to notify of any changes.
Unfortunately, currently, no standardised mechanism for advertising your feed to the rest of the world exists.
The Geofeeds are much easier to administer than the geoloc entries. The Geofeeds are just a flat file that can be edited at speed. At the same time, geoloc entries are troublesome to manage at scale (i.e., when you subdivide IP blocks that are then in use at different locations) as they require separate objects in the whois databases.
