Upon closer inspection in the FreeBSD sources found at
<http://www.freebsd.org/cgi/cvsweb.cgi/src/lib/libc/net/getaddrinfo.c>,
I think it's the numeric hostname that caused the problem.

That particular issue was fixed in FreeBSD 5.4/6/7, with MFC
getaddrinfo.c version 1.55 (January 2005). I am requesting a backport
for 4.10, 4.11, 4-STABLE and 5.3 from the FreeBSD security officer.
