Folks, The IETF has recently passed draft-iana-rfc3330bis-08. This draft documents the fact that the following address ranges have been reserved for documentation: - 192.0.2.0/24 (TEST-NET-1) - 198.51.100.0/24 (TEST-NET-2) - 203.0.113.0/24 (TEST-NET-3) In addition, some authors have used 128.66.0.0/16 (TEST-B) for example purposes. There is no RFC that talks about this block, but my understanding is that IANA/ARIN have marked it as reserved. If you search the Internet you will find at least some number of examples and firewall rule sets that use this block, but I have no good idea about how widespread such usage is. What should we do about this block? Some of the potential answers include documenting its role, marking it as reserved but deprecating its use in examples, and returning it to the free pool immediately (with a warning sign about possible filtering problems). Comments? Ron
