[ppml] ARIN Board Advises Internet Community on Migrationto IPv6

[Anthony A. Crumb]

I think it is great that we are spreading the word, and I am glad that 
ARIN has made this announcement. Now we need to put the issue ULA-central 
or ULA-local to bed. I am sure that I will not be able to justify more 
than one /48 globally routable prefix for my US internet presence. Because 
the last 64 bits of the address are required for interface identifiers 
that only leaves me with 16 bits with which to create a hierarchical 
enterprise address allocation model. 16 bit of subnetting space is not 
enough to create subnet allocation model for a large enterprise. It would 
seem to me that I would want to use the globally routable /48 for internet 
facing environments and some form of ULA space internally. We try very 
hard to employ only RFC based solution in our environments. When are we 
going to see an end to the debate over ULA-Central and ULA-Local? I have 
been working with RFC4193 "random" method to create address space for my 
internal networks but I do not want to move forward with deployment until 
there is some "ratified" RFC in place that helps to guild my address 
allocation strategy. To be blunt I don't have time to go through the 
effort of building a design just to have to rework it because the space 
the RFC4193 defines and ULA-Local gets broken up and allocated to RIRs, 
LIRs, ISPs, and or carriers to hand out as ULA-Central. I want to adopt v6 
and get started but I can't afford false starts and rework. Anyone else of 
like mind, or opinion?

Congratulations to the Board for their historic pronouncement related to 
IPv4 and IPv6 address management.

I hope that this announcement was forwarded to the media as well as 
ARIN-announce.

And, I hope that each of you consider forwarding their announcement to 
your customers and community media.
