I have done some research:
I think I know what global unicast addresses are.
My ISP grants me 2605:6000:FFC0:7D:C4CD:A25A:777A:xxxx/64 (at least that is what my router reports as its "IPv6 address" (TP-Link AX1800).
Further down the page I see my "Lan Address Prefix" as 2603:8080:2C05:209A:: with it reporting an address of 2603:8080:2C05:209A:EA48:B8FF:FE1F:6DF0/64. While this confuses me (this is a range, right?), my question is:
Why isn't my lan address prefix 2605:6000:FFC0:7D::/64? I would love to have global unicast addresses for each host/interface.
From what I understand, each of my devices can get a /64? They don't need that! They can get a /80 and I can have subnets, right?
I understand why I am getting addresses on my PC like:
inet6 2603:8080:2c05:209a:14a9:d676:62f6:xxxx/64 scope global temporary dynamic
valid_lft 300sec preferred_lft 300sec
inet6 2603:8080:2c05:209a:7d63:7c25:af1d:xxxx/64 scope global dynamic mngtmpaddr noprefixroute
valid_lft 300sec preferred_lft 300sec
inet6 fe80::56a3:67f2:bc72:52c7/64 scope link noprefixroute
valid_lft forever preferred_lft forever
But why do I have 2? Why are they not under the WAN IP prefix?
If this is something the router doesn't support, I don't mind using OpenWRT.
