Amber Upstream Light
I have a C6300 AC1750 modem & router with firmware version 2.01.20 (I think this is the most current version). The upstream light is amber, and I find that I occasionally have connectivity problems. ...
If you're using it for pihole, why would you be concerned?
In terms of the ipv6, certain parts of it are for the global and others for local.
And if the pihole is set with the specific ipv6 address for that computer, it shouldn't be changing. I've been using it for over a year without issues.
The IPv6 GUA network prefix (the one you pointed out in your original reply) is not static and is in part delegated by Comcast (my ISP). But to your point, just because they can change it doesn't mean they will. It will depend on your location, your ISP and I think your modem how frequently it changes. I would see using the GUA as a temporary solution.
You can point devices on your network to a DNS server using any of the server's IPv6 addresses (e.g. Global, Unique Local, or Link Local) so why not choose one that is not influenced by your ISP? Choosing a fe80::/ or fd00::/ address is the preferred route for those that have a router willing to accept a non-GUA address, and is the reason I'm asking here how to make my Netgear router do the same.
No fix other than getting a new modem.
