Renumbering is a fact of life on the Internet. People should be prepared to renumber, and technologies that facilitate easy renumbering should continue to be developed. That said, even if it were possible to renumber gracefully at any time, reducing the frequency and scope of renumbering is not in itself a bad idea. Therefore, I have no problem at all supporting an allocation policy designed to allow growing networks to undergo fewer renumberings, and to allow networks with many levels of administrative authority (as in the case of an ISP with downstream customers, some of which may also have downstream customers) to undergo nearly none. What appears to be the correct approach now has been outlined by Karl and implemented by RIPE. The test for who should get a minimum portable allocation unit (/19 these days) should be the only thing argued about. It should be easy for any ISP to obtain an initial allocation, and somewhat less easy for entities which do not re-allocate address space to others. Sean.

Karl's assertion is that adopting a RIPE-style system where for a fee anyone who is an ISP can get a small allocation of portable space, and add other allocations over time, is a practical solution. I agree completely. Sean.

Like MCI, Jon will not need to renumber out of a /14. You only have to ever renumber out of small blocks. A /20 is not hard to renumber. -- Shields, CrossLink.

Karl makes a real good point, renumbering places an un-needed burdon on the customer; one they never asked for, and probably never expected. I imagine stuff like this will just cause more and more customers to move into environments with NAT, or encourage them to join the bigger networks where renumbering would be less likely. -Jamie (speaking only for myself) -----Original Message----- From: Karl Denninger [mailto:karl@mcs.net] Sent: Saturday, May 16, 1998 10:35 PM To: Michael Shields Cc: Jon Lewis; jamie(a)ais.net; Jeremiah Kristal; nanog(a)merit.edu Subject: Re: ARIN allocating /20 netblocks?

I admit it if the perspective is to build all or a part of the WIN NT suites in a kind of a hardware or ASIC is not clear for me, the questions that I would like to raise: What version of WIN NT? is it 4.0 or beyond..? How do we expect customers will be confident enough to make this step?, Is WIN NT reliable, stable in a customized ASIC hence WIN NT would be more suitable than the general purpose hardware architecture?. Implementing standard IPv4 services on the ASIC and optimizing that still on its early stages; i.e., mostly for inter LAN routing. So, do how that will work for WIN NT?. Let's do it for multi-routed protocols in the ASIC switches and think further for the high-level embedded applications. I agree it might be a good idea if embedded NT is doing a single task such as Web caching, but not a "full fledge" switch/router. Ehab H. Hadi Northern Telecom, LTD.

I know of at least one case where a customer cannot (will not) renumber out of a /24 because they (without commenting on the intellectual prowess of this particular act) shipped a million CD's with the .128 IP address in that class C hard coded into their game. Sure, it's only one IP, one machine to renumber, but... Owen
