Episode 46: The Fullbogon Feed

Today we announce a significant addition to our bogon reference project. The new portions of the project are offered at no cost to the community, and the original bogon lists and feeds are not
being changed or canceled, just augmented.

Our new "fullbogon" feed includes prefixes allocated to RIRs, but not assigned by the RIRs to end-users, ISPs, etc, providing a more complete view of the unassigned space that should not be seen on the Internet.

This new service is therefore more granular than the original feed, including a wide variety of non-routable prefixes as well as unassigned prefixes and it also includes IPv6 prefixes.

Simply email bogonrs@cymru.com with your ASN, peering IP addresses and whether you use MD5 authentication.

See an overview in this weeks show, as well as a more basic overview in episode 12. For a more detailed explanation, see
http://www.team-cymru.org/Services/Bogons/.

Even more so than the original feed, there are significant changes to the list every day and the feed automatically recalculates the prefixes as they are allocated from the regional registries, so make
sure you are able to regularly update your lists.
