It belonged to some Canadian ISP, I believe it was a cable company. Regarding the aggregation/deaggregation mess. This is due to the fact that ARIN is rather strict with IP assignements and how we route internally. Because ARIN wants us to use 80% of our ip blocks, before we can request new assignments from them we have to dole out addresses in /22's to each city we have, in order to use them up appropriately. Its been a bit of a nightmare trying to meet ARIN's policies and also try to meet the Internet Communities policies. Believe me, I would much rather advertise a /16 prefix out to the Internet, rather then a /22. We have not been able to accommodate this unfortunately. -----Original Message----- From: Jon Lewis [mailto:jlewis@lewis.org] Sent: Wednesday, July 06, 2005 10:31 AM To: Sanfilippo, Ted Cc: nanog@merit.edu Subject: Re: SORBs On Wed, 6 Jul 2005, Sanfilippo, Ted wrote:
Does anyone know of an easier way to remove IP blocks from a blacklist? We received a /16 from ARIN in May and have been trying to get SORB's to remove the blacklist association on these addresses. They seem to take forever to remove the blacklist association.

Any chance of this deaggregation mess getting cleaned up? I've contacted sorbs on your behalf, assuming the /16 concerned is 63.138.0.0/16. This raises a question that interests me as someone who had to deal with recently bogon space last time I got ARIN space. 63/8 was assigned to ARIN in 1997. Much of it appears to have been assigned to ARIN members in the late 90s and very early 2000's. How did Paetec happen to get a /16 from 63/8 in 2005? Was this recently reclaimed from some defunct company (which could explain the sorbs dul listing), and Paetec just got lucky? ---------------------------------------------------------------------- Jon Lewis | I route Senior Network Engineer | therefore you are Atlantic Net | _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________
