1) They say that they are hindered in their renumbering by not being able to get a large enough block of addresses from ARIN (I forget the exact wording). Does this mean that NAC were lax with their IP allocation policy and let the customer have more addresses than ARIN policies would otherwise allow? If their new allocation is really the biggest issue, why not just go back and ask ARIN more nicely?
I've seen similar claims by others before. Having gone through the procedure myself, I'd guess one of two cases. 1) Pegasus did a poor job with their ARIN-NET-ISP request and failed to convince ARIN that they were efficiently utilizing the amount of PA IP space they wanted to replace with PI and renumber into or the speed with which they intended to renumber. 2) ARIN gave Pegasus an initial allocation insufficient to cover their entire network with the understanding that Pegasus would begin renumbering and do another ARIN-NET-ISP request when they'd used up the initial allocation and returned a similar amount of IP space to NAC. I doubt anyone will comment as to which of these is closest to reality. Case 2 wouldn't surprise me at all when the space involved is much more than ARIN's minimum allocation.
2) They say they have to write custom software to allow the renumbering. Is this related to them having to fit into a smaller address block? Otherwise, I don't see why there's such a big issue about having to write *new* software because of an IP renumber.
They probably either meant custom software (perhaps just shell scripts) to partially automate parts of the renumbering process, or that whatever software they use on their hosting resale systems is somewhat inflexible with IP addressing and would need to be hacked to deal with dual IP blocks during the transition. ---------------------------------------------------------------------- Jon Lewis | I route Senior Network Engineer | therefore you are Atlantic Net | _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________
