[sudo-sys] Do we have an ipv6 prefix?

[Yardena Cohen]

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

$ ip -6 neigh show

Can you help us get set up?
