To be fair… supporting dual stack really does suck
A lot about networking sucks, but that's what people are paying them for.
Not really, ISPs (who are on nanog) tend to like ipv6. The ones who complain are sysadmins and network operators of campus/corporate networks.
They've only had over a decade to get their act together. I'm being generous, seeing IPv6 is older than the original IPv4 internet was when it went mainstream.
Also to be fair, IME there seems to be a lot more vocal pro-IPv6 people on the NANOG list than not.
