Perl regular expression to match an IP address

Question

I have written this code, but it does not work. Can someone point out the issue?

sub match_ip()
{
  my $ip = \"The IP address is 216.108.225.236:60099\";
  i         


        

Answer 1

$ip = "10.255.256.1";

# will accept valid ips
if ($ip =~ m/^([1|2][0-9]{1,2})\.([0-255]{1,3}\.){2}[0-255]{1,3}/ && ($1 <=255)) {

  print "This is a valid ip: $ip \n";
 } else {
   print "This is not a valid ip: $ip \n";
}
