How to force rapid ipv6 adoption

Nothing to do with religion at all. I advocate IPv6 all the time as some one who deals a lot with SIP. The issues are endless when dealing with NAT. NAT is an ugly hack and should die already. It will take a few years for router manufactures to get it right but them they do it will be better for all.

i'm still confused, to be honest.

why are we 'encouraging' 'evangelizing' or 'forcing' ipv6 adoption.

it's just a new addressing protocol that happens to not work with the rest
of the internet.  it's unfortunate that we made that mistake, but i guess
we're stuck with that now (i wish i could say something about lessons
learned but i don't think any one of us has learned a lesson yet).

so people will renumber their network assets into this new network
namespace when either:

1) the new non-internet ipv6 network has enough good stuff only on it that
it makes sense to go over there; or

2) the old ipv4 internet addresses get so expensive that ain't no one
willing to pay.

right now, neither of those things are true.  so people who are adopting
ipv6 are doing so for two reason:

A) blind, unmotivated religious reasons.  they "believe" in this new
protocol and have somehow managed to tie their identity up in it.  (this is
clearly a mistake for an engineer:  technology comes and goes.  don't ever
tie your identity up in some technology or you'll end up advocating DECNET
for the cloud at some point.  it won't be pretty).

B) strategic reasons.  there are people who think that switching costs are
going to be high and that there's an advantage to moving earlier to be
ready for coming demand when #1 or #2 above happen.  unlike A, B is
completely rational and smart.  it might be wrong, but it's not stupid at
all.  put mike leber and HE in this B category.

the only reason people are *advocating* ipv6 right now are that they've
made a religious choice, which is weird and should be a personal, not
public choice unless they are great commission ipv6 adherants [1], *or*
they have a vested interest in getting your business.

the first reason is religion and is off-topic for nanog and the second
reason is marketing (however well intentioned) and should also be off topic
for nanog.

so can we stop talking about ipv6 advocacy and move on to the network
engineering topics, please?  if someone is running ipv6 for whatever reason
and has questions, awesome.  if someone wants to talk about addressing
schemes, awesome.  but trying to convince someone to run LAT^H^H^Hipv6 or
whatever disconnected network protocol they're advocating today?  not
