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.

 VS> Do you see the WAN address of the router in the `traceroute -6` output?

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:

  1     1 ms     1 ms     2 ms  2607:fea8:ab00:e1c::1
  2    14 ms    18 ms    13 ms  2607:f798:804:2eb::1
  3    14 ms    12 ms    13 ms  2607:f798:10:e420:0:241:5615:1161

  9    17 ms    73 ms    17 ms  dns.google [2001:4860:4860::8888]

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.
