So I'm guessing you only work on Enterprise networks?

Most enterprise networks don't have the problem IPv6 solves - not enough
IPv4 addresses - because they're using RFC1918 private addresses in
combination with NAT.

Places where IPv6 is being deployed are where private IPv4 addresses aren't
adequate or where NAT capacity is expensive - primarily residential ISPs
including on mobile networks.

Nearly 50% of Google's access is over IPv6:

APNIC are also measuring IPv6 use:

If you think IPv6 isn't being deployed and used, you're just not looking in
the right places.

Regards,
Mark.
