[ppml] "Who's afraid of IPv4 address depletion? Apparently no one."

[Randy Bush]

can we get real here?  what is the likelihood of someone *major* putting 
up a service only reachable over ipv6?

people will move when it is in their business interest to do so.  what 
does it take to make your enterprise dual stack?  john, how far have you 
progressed?  given the government is your big customer, i presume you 
have gone in early and big.  care to tell us how easy it was and how 
much it really benefits beyond a check-box?

we went in early, in fact the earliest commercial roll.  and we have 
regressed, i.e. some services are not maintained over ipv6 that used to 
be because no one used them and they caused pain.  try an smtp service 
with no ipv6 dnsbl, etc..  we're working on changing that, but it's not 
easy to justify.

drc, with great political and bureaucratic pain, has been rolling ipv6. 
so he has his money where his mouth is.  how are the rest of the mouths 
here?

before getting on high horse, check for saddle or be damned good at 
bareback on a damned tough horse.
