ok, your regex seems to come straight from the pages of
the
Owls Book. why did you insert that dot star at the end?
it want alter the match in any way, it just captures the
rest of the string in $5.
one problem you might have a look into is the context
of your matching. for example, strings like
"2243423423.23.23.2312blabla34" or "1.2.3.4.5.6.7.8.9"
will match even though they probably don't contain what you
want to match as a valid ip address.
