What is inconsistent is that ping will not resolve the address but
drill will. The only nameserver defined in /etc/resolv.conf is
127.0.0.1.  We never get to the point of determining if the target
replies to the ping.

pkg.freebsd.org happens to be the domain that I used to test whether
or not ping could resolve.  I get the same results irrespective of the
domain used.
