( #3333=superdoc: print w/replies, xml ) Need Help??

I went to report the doc error, and found a major, easy-to-fix bug that's been ignored for two years. ipv4_chkip will pass any string of four or more integers between 0 and 255 connected by .'s. The deal-breaker here is the 'four or more' instead of 'exactly four.'

So I can't recommend it. Perhaps try Regexp::Common instead.

use Net::IPv4Addr qw(:all); use Regexp::Common qw(net); my @var = qw( 12324.123.12.1; print "Net::IFv4Addr:\n"; ipv4_chkip($_) and print "$_ is good\n" for @var; print "Regexp::Common:\n"; /^$RE{net}{IPv4}$/ and print "$_ is good\n" for @var;


Net::IFv4Addr: is good is good Regexp::Common: is good

Note that you do need to anchor the start and end of the regexp with ^ and $, 'cause just /$RE{net}{IPv4}/ would match 312.45.32.4.

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
