Hello, As many of you all might known, LACNIC has been allocated the block 201/8 from IANA back in April/2003: http://www.iana.org/assignments/ipv4-address-space it was announced in this mailing list: http://answerpointe.cctec.com/maillists/nanog/current/msg01094.html But, some users are facing problems with addresses in this range due to old filters in some backbones. There was recommendations and routes configurations tips in which the 201/8 block used to be referred as bogus route. At the time those documents were created, the mentioned blocks was not allocated by IANA yet. What is not true since April/2003. Based on this, we would like to ask to network administrators in general to revise their router configuration to make sure they are not filtering valid routes, like networks into 201/8 block. Thank you.

Hi, NANOGers. ] Based on this, we would like to ask to network administrators in ] general to revise their router configuration to make sure they are not ] filtering valid routes, like networks into 201/8 block. Team Cymru provides a bevy of methods to keep up with prefix allocations. Our personal favorite is the bogon route-server project, but feel free to pick any or all of the data feeds. You will find all of them listed at the following URL: <http://www.cymru.com/Bogons/> We hope this helps! Thanks, Rob. -- Rob Thomas http://www.cymru.com ASSERT(coffee != empty);

Some folks (like me) verify assignments based on published data from the RIRs. Checking your FTP site for delegated prefixes as they show up in the DNS, I see this in the zones directory: -rw-r--r-- 1 ftp ftp 653 Dec 23 11:58 170-LACNIC -rw-r--r-- 1 ftp ftp 187 Dec 23 11:58 170-LACNIC.asc -rw-r--r-- 1 ftp ftp 52 Dec 23 11:58 170-LACNIC.md5 -rw-r--r-- 1 ftp ftp 214 Dec 23 11:58 199-LACNIC -rw-r--r-- 1 ftp ftp 187 Dec 23 11:58 199-LACNIC.asc -rw-r--r-- 1 ftp ftp 52 Dec 23 11:58 199-LACNIC.md5 -rw-r--r-- 1 ftp ftp 1478 Dec 23 11:58 204-LACNIC -rw-r--r-- 1 ftp ftp 187 Dec 23 11:58 204-LACNIC.asc -rw-r--r-- 1 ftp ftp 52 Dec 23 11:58 204-LACNIC.md5 -rw-r--r-- 1 ftp ftp 108 Dec 23 11:58 205-LACNIC -rw-r--r-- 1 ftp ftp 187 Dec 23 11:58 205-LACNIC.asc -rw-r--r-- 1 ftp ftp 52 Dec 23 11:58 205-LACNIC.md5 e.g. no zone data for 201.0.0.0/8 - so at least from here, we will filter 201.0.0.0/8 until we see valid DNS data. --bill
