But nameservers could be v6 addresses nevertheless, and the values are
stored in the _ext.nsaddrs member these days. Our definition of
_res_state does not define all the members of _ext as GLibc defines,
though, and our resolver code doesn't use _ext at all, afaics.

Except, the value has no meaning for ipv6.
