FWIW for other onlookers that this thread might attract... It should be noted that, in order filter out only valid IP addresses; one needs to modify the RE above: Take note of the additional anchor(s) in the second line. Difference being; in the first line, the filter is an RE for any-and-all-digits && only-digits-3-or-less-in-length. While the second filters for: <=3-in-length && <=255-in-size. HTH --Chris #!/usr/bin/perl -Tw use perl::always; my $perl_version = "5.12.5"; print $perl_version;
