In short, a magical wand and a cast should get you sorted out...
unless you ask for a more scientific approach on the freebsd-questions
list ;-) Sorry, obligatory disclaimer... :-)

So you're definitely the wizard on this list... :-)

A command you can try is traceroute, which will show you what
your system does to resolve the name. nslookup should also
