IPv6 not working on new FttH

Hi. Our internet service currently uses IPv4 addresses. Please make sure the device you are attempting to connect is capable of receiving an IPv4 address from the network. Thanks, Lisa Cox Support Forums Moderator

A Cox technician that came on-site used (what I think was called) "Home View" to see what IP address was associated with my service, and he saw only the IPv4 address. He checked another unit in the same apartment building and also saw only IPv4. But when he checked an address he recently visited and remembered having the same model ONT, he could see IPv6 addresses allocated. That was finally something that let them escalate this, and engineering resolved it (probably at the router, probably DHCPv6 relay). A couple things, several Cox technicians thought the ONT has something to do with IP address allocation, but the Nokia ONT is bridge-mode, does not assign addresses, and I was seeing IPv6 router advertisements. They also thought that not having anyone else report a problem from the same node pointed only to the ONT in the unit, but dual-stack computers are very good at falling-back to IPv4 so most people will not notice when IPv6 is not working correctly.
