This is close to my perception -- which is why I somewhat harshly advocated for the document to be caught and non-sent to IESG. My apologies for choice of words. In this situation I am pretty convinced that we have to deal with varying cost tradeoffs more than finding Graals of address supply management. I think that the price paid for "wasting" global address space by filtering it off at the IGP edge in order to create non-routed (as opposed to non-routable) address space is worth paying. Having recently been provoked in bit-flipping directions by external input I do see a need for stating *why* I oppose creating dedicatedly local addresses - it is simply going to occur crashes between mirror worlds. The discussions on LL address usage are typical for this -- the LL scope was created to cater to specific functions (RA et. al.) but the distinction is blurred as soon as the notion "an address is an address is an address and as long it is unique I can use it pretty much as I please." takes over peoples minds. It sure has taken over my brain and it is quite contagious, on both sides of this long debate. Thus, there is an operational requirement to remove potential sources of ambiguity because the usage patterns for addresses tend to approach a state where every service may be deployed on any address. P2P certainly is a prime example. Good arguments have been made that this is simply a failure to release v4 paradigms, and I'm tempted to agree -- but that does not mean we have a solution to this except forcing uniqe address space onto users and programmers. -- Måns Nilsson Systems Specialist +46 70 681 7204 KTHNOC MN1334-RIPE Are the STEWED PRUNES still in the HAIR DRYER?
