Hi Mike.  I don't think Nmap has a way to get that information right
now.  And plus the name put in by the user (if any -- putting in IPs
and networks is probably at least as common as names) isn't
necessarily any more likely to be the web server's official hostname
than the name obtained from reverse DNS.

Your 302 approach actually sounds like a promising idea.  If you find
the best name, you could save it in the registry for other scripts.
Also, we're looking at command line options for specifying variables
like this.  So your script could first check if a ServerName variable
was set, and use that if it was.  Otherwise, it could fall back to
Nmap's host.name.

Thanks for your feedback!

Cheers,
