Hi, I'm writing from Sudo Room in the Omni Commons (4799 Shattuck, account #10261). We've been using a static ipv4 address (142.254.26.9) to serve our large building for many years, and we'd like to start supporting ipv6 as well, but we're not sure what prefix we've been assigned, if any. Our router is only advertising link-local, as you can see here: $ ip address show dev enp3s0 2: enp3s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether 00:25:90:03:1f:66 brd ff:ff:ff:ff:ff:ff inet 142.254.26.9/24 brd 142.254.26.255 scope global enp3s0 valid_lft forever preferred_lft forever inet6 fe80::225:90ff:fe03:1f66/64 scope link valid_lft forever preferred_lft forever $ ip -6 neigh show fe80::223:6aff:febe:5932 dev enp3s0 lladdr 00:23:6a:be:59:32 router STALE $ rdisc6 -m enp3s0 Soliciting ff02::2 (ff02::2) on enp3s0...
