Don't try to search for the form of the IP address in the string, use the "http:" and URL delimiters in the regex: 
$host = m#http://([^/]+)*#;

That will also select a hostname if the URL is something like "http://foo.bar.com/foo".

HTML::Parser is a better solution, but the above would still work if you're forced into parsing non-conformant HTML.
