Hmm what if it doesn't? Which is the case any many scenario. My thoughts
are:
If www.commandprompt.com is allowed, then the ip address 207.173.200.129
is allowed to connect.
If we go the reverse way:
129.200.173.207.in-addr.arpa name = 129.commandprompt.com.
Which really isn't that useful imo.

Hmm interesting. I wouldn't expect that. I might
expect .commandprompt.com to mean *.commandprompt.com. But
commandprompt.com I would expect only whatever the A record returns as
commandprompt.com.
One thing I don't want to do is create a bunch of different style
syntaxes that are available :)
