The IESG has received a request from the Global Routing Operations WG (grow) to consider the following document: - 'Time to Remove Filters for Previously Unallocated IPv4 /8s' <draft-ietf-grow-no-more-unallocated-slash8s-03.txt> as a BCP The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2011-10-12. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract It has been common for network administrators to filter IP traffic from and BGP prefixes of unallocated IPv4 address space. Now that there are no longer any unallocated IPv4 /8s, this practise is more complicated, fragile and expensive. Network administrators are advised to remove filters based on the registration status of the address space. This document explains why any remaining packet and BGP prefix filters for unallocated IPv4 /8s should now be removed on border routers and documents those IPv4 unicast prefixes that should not be routed across the public Internet. The file can be obtained via http://datatracker.ietf.org/doc/draft-ietf-grow-no-more-unallocated-slash8s/ IESG discussion can be tracked via http://datatracker.ietf.org/doc/draft-ietf-grow-no-more-unallocated-slash8s/ No IPR declarations have been submitted directly on this I-D. _______________________________________________ IETF-Announce mailing list IETF-Announce@ietf.org https://www.ietf.org/mailman/listinfo/ietf-announce
