Hi, I have been following this discussion for a few days now, and it has struck me that there has been little discussion about the *monetary value* of large blocks and aggregations to participants. Such a discussion could lead to "charging the polluters" of the number space. E.g. it seems obvious that a PI block is more valuable than a PA block of the same size, an an unfragmented block is more valuable etc. Cost concious organisations could then be better motivated to clean up their act. A little research turned up a paper called: SUGGESTIONS FOR MARKET-BASED ALLOCATION OF IP ADDRESS BLOCKS. By Paul Resnick, 1995. Has anything ever resulted from that discussion? My personal/professional reason for being interested is not so much in the operations of registries and providers, although i was involved in that area at one time. I have clients running serious internal WANs (100+ sites, 10.000+ seats, multiple internal IT organisations), who face serious challenges in (re-)allocating number space internally, even on (or especially on?) private range blocks (e.g. 10/8). Any insights into guidelines might be carried over to network management policies internal to those organisations. Adrian's proposal reminded me of the insight that our current 32 bit IP addresses have already in effect been extended to something like 48 bits using NAT. 24 bits address an organisation, within which an additional 24 bits (in a 10.0.0.0/8 network) are used to address individual nodes. For your insights i express my gratitude.

I still can't see why the idea of having own netblocks and AS for multi-homing customers breaks if one ISP is going south. But of course there are other and more financial drawbacks with this approach.

The new mantra is: go home and do your homework

I agreed with Arnold, that networks should be able to muli-home without the feeling that they are breaking the Internet.

Of course that is sadly the case today. So, as per Arnold's suggestion, I did some homework on an alternative solution, basically to IPv6. This is only the first thoughts, just to get the main points across. Its is far from complete!

If you can spare the time, wander to,

and see what you think.
