I wouldn't bet on it staying the same. The external IPv4 address will stay the same for months at a time; I don't expect any different for the IPv6 network > If you can potentially get a different /56 or different /64 > delegated then you have no real choice but to use DHCPv6. *sigh* The dhcpv6 server on the netgate allows for static mappings like <duid> ::1:10 where it fills in the network/64 portion from the delegation and uses the ::a:b:c:d for the host address.
