in thread How regex works in array mode?

I already replace it and the output is:

ip:192.168.243.1

but it doesn't print the "ip:192.168.243.2" Is it possible to print the next value in the array? Thanks

or is this output possible?

ip:192.168.243.1 ip:192.168.243.2

    Perhaps you haven't replaced it correctly?
    use 5.010; my @lines = ("ip:192.168.243.1", "ip:192.168.243.2" =~ /(ip:[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3})/); say for @lines; __END__ ip:192.168.243.1 ip:192.168.243.2
    Do note that ip:192.168.243.2 is in @lines only because the pattern matches the entire string. And do note that "ip:192.168.243.1" is not subject to any matching. In fact, the assignment to @lines is equivalent with:
    my @lines; $lines[0] = "ip:192.168.243.1"; push @lines, $1 if "ip:192.168.243.2" =~ /(ip:[0-9]{1,3}\.[0-9]{1,3}\. +[0-9]{1,3}\.[0-9]{1,3})/;
