I run Comcast and run IPv6 on gear behind my router/firewall. I have a static assignment of both IPv4 and IPv6
I can't tell you how CL does it but I think it's similar to how Comcast does it. For non-static assignments, SLAAC is all you get. Meaning you cannot run 100% IPv6 since there's no way to auto-assign DNS server IP's via SLAAC You also cannot run IPv6 behind your OpnSense router even if you subnet the /64 you get (or whatever you get) because Comcast will not recognize IPv6 packets not sourced with the /64 that they hand out via SLAAC (even though they might be legitimate packets and you have configured your OpnSense router to route them) All IPv6 must be sourced from your OpnSense device If you rent Comcast's router then you can get IPv6 behind it. But then you have to use their gear. For static assignments, you use DHCPv6-PD I won't go into how that is setup because it's long and technical and hardware dependent but it does work. And yeah using IPv6 I could have more statically addressed IPv6 servers behind my Comcast line than there are grains of sand on all the beaches in the world, etc. etc. Comcast will also install IPv6 PTR records on request so email servers can be happy using IPv6.

You use either Stateless (SLAAC) or Stateful (DHCPv6) configuration. -Ben On Sunday, September 29th, 2024 at 8:11 PM, Courtney Rosenthal <[email protected]> wrote: > I'm a recent customer for Quantum Fiber.
