alt Hacker NewsI had working IPv6 in the past, but currently I seem to have no working IPv6. Using Xfinity. I have access to some servers at a friend's place in another city, pretty sure he also doesn't have IPv6. Maybe some phone calls would sort it out, but when "everything" still works (with IPv4), it's hard to care.
That is really bizarre, because I have Comcast and I find their IPv6 support excellent. The only complaints I have are that I wish you could get bigger than a /60 prefix (a /56 would be nice), and that I wish it was feasible to get a static prefix as a residential customer. Granted you said you don't really care to fix it, but if that ever changes I do think you could get them to fix it pretty easily. IPv6 is one of the things they generally do right.
