Comment on Why does my ISP sometimes give one IPv6 and another with a different subnet?
Zikeji@programming.dev 2 weeks agoAh - yeah the /128 is what the ISP used to route traffic to your router. I believe that’s IPv6 PD (prefix delegation) - the router uses DHCPv6, gets given that /128 it’ll use for the ISP, then the ISP delegates the /64 (or other sizes) to the router.
