ipv6 delegation from Comcast business modem stopped working
On about Nov 18, my modem stopped delegating prefixes to my pfsense router. I spent several days trying to get the issue escalated, and it finally landed with [Edited: "Personal Information"] Michele <[Edited: Language]>. She sent a tech to urgently replace my modem, and the new modem worked (successfully delegated to my router) for about an hour UNTIL it got the same update. The new modem caused me to get a new ipv6 prefix, requiring me to spend an entire day purging the old one from freeipa and lots of other places--and that was totally unnecessary because there was nothing wrong with the original modem. My previous ipv6 reverse delegation was delegated to my own nameservers, and the new one doesn't work, of course. Michele did say that I would hear from the advanced DNS team within 24-48 hours, but I didn't, of course. I am now left with two big problems, and Michele has stopped responding to me:
1. I'm still not getting subnet delegation from the comcast modem to my pfsense router.
2. Reverse DNS is still delegated from my old ipv6 prefix, but is not delegated from my new one; thus I have no ipv6 reverse lookup.
This is VERY frustrating. Does Comcast not test the firmware before rolling it out?

My IPv6 changed the other day and I noticed the same thing. Also using Pfsense. My WAN did pick up the new address, but nothing else on the LAN (Track interface, RA and tried DHCP6). It's not as urgent for me at the moment, thankfully
