State of IPv6 prefix delegation functionality on current business modems
Hey folks, I'm just checking in to see what the latest state of IPv6 is on business class. I recall having a bear of a time getting IPv6 to work on a Technicolor gateway about 5 or 6 years ago, and have not had to configure IPv6 on a Comcast Business network since then, but might be doing so soon. Do the modems support prefix delegation of at least a /60? Is there any speculation that *gasp* true static IPv6 will ever be offered? Thanks in advance. (Also like that the pinned post is over a decade old here. I miss NetDog!)

They do a /56, but don't allow us to setup our own routes. We have to use their DHCP PD, we get /64's out of it and we have to deal with the rotating subnets.
There is a post here about setting everything up manually, but it doesn't stick, the cable modem will eventually stop routing packets to your network.
I did a deep dive on that and concluded that if they would only accept and process a RA from our router properly it would work. But they don't.
Currently looking at finding another provider.
