When looking at the RFC [1], there's no mention that this can't be the
gateway address.  Permit it.

The first address in an IPv6 network is now a valid, usable IP for routers.
It had previously been reserved, but now can be assigned to a router so
that an IPv6 address ending in "::" could be a valid default route.
