IS THE BELOW CORRECT? 
my $str = 'BIG BIG DATA FILE';
 if (my @matches = $str =~ m{ ([0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-
+9]{1,3}:[0-9]{1,5}) }xmsg) {
   print qq{matched @matches};
   }

It will extract all occurrences of what you define as an 'ip address' to the array.

BTW again: It is better to reply to a post immediately after (and 'below') the post rather than as an addendum to the OP: makes the conversation a lot easier to follow.
