Perhaps you haven't replaced it correctly?
use 5.010; my @lines = ("ip:", "ip:" =~ /(ip:[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3})/); say for @lines; __END__ ip: ip:
Do note that ip: is in @lines only because the pattern matches the entire string. And do note that "ip:" is not subject to any matching. In fact, the assignment to @lines is equivalent with:
my @lines; $lines[0] = "ip:"; push @lines, $1 if "ip:" =~ /(ip:[0-9]{1,3}\.[0-9]{1,3}\. +[0-9]{1,3}\.[0-9]{1,3})/;
