I complained as a yearly tradition for couple of years to get v6 enabled in my ISP. They had the core network enabled on World IPv6 Launch in 2012, but not deployed to end customers.

One simple way to check if your ISP have some kind of IPv6 netowork is to see if CDN domains given by YouTube and Facebook have AAAA records.

We shouldn't have to ask for ISPs to add IPv6 support but here we are.
