I don’t think they have a clear policy for V6. I can tell everytime my Comcast cable modem is updated because I lose all ipv6 connectivity. Right now I am in one of those periods. I can’t get ipv6 to pass the modem. Customer support tells me it’s not an issue and must be on my end. My he.net tunnels won’t even work.
