Complete absence of data of one kind causes the +# appropriate default information to be used.

Given +# the precedence of IPv6 over IPv4 (see below) on machines having only +# site-local IPv4 and IPv6 addresses a lookup for a global address would +# see the IPv6 be preferred. The result is a long delay because the +# site-local IPv6 addresses cannot be used while the IPv4 address is +# (at least for the foreseeable future) NATed.
