<br><font size=2 face="sans-serif">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?</font>
