On my router I show a /128 address on the WAN interface and a /64 address on the LAN interface.  I've played around a bit with this and I can request a /56 from my ISP and split that up into multiple /64's on subinterfaces.

I see the ::1/64 address from the LAN interface:

>tracert -6 dns.google

Tracing route to dns.google [2001:4860:4860::8888]
over a maximum of 30 hops:

The current /128 address on my WAN interface is 2607:f798:804:2eb:19b0:e74b:fc6:d707/128 so it looks like hop 2 is the ::1 address from that prefix.
