Hi,

Well, I see lots of (even small) enterprises that have *collisions* on
IPv4 all over the place - mergers, VPNs to partners, etc. - and of course
workarounds are found, like "double NAT on VPN links", leading to extra
costs that people take for granted.

Add to that the usual problem of "how big do I size my subnet", which
is also needless annoyance from the past.

I don't think running IPv6-only inside an enterprise can be done today
(legacy applications being the largest obstacle, plus inertia on the
side of enterprise network admins), but I do see quite some benefit
in having IPv6 - and if I have that, I want to get rid of IPv4 as fast
as possible.

We started using IPv6 in 1997.  Your point being?

have you enabled IPv6 on something today...?
