Your right Doug, didn't bother taking box down after changing to new format, it works as expected, ignoring duplicate aliases regardless of protocal. I've regrouped my configs into interfaces instead of protocals now for the change so ipv4/6 aliases can be seen together without making mistakes. Definately would be nice to see ipv6_addrs_<ifname> added.
