I am trying to build a regular expression for below files.

HIGH-LEVEL Status file for process (can be in below formats)

server_load_<ipaddress>.<ipaddress>.SKIP
server_load_<ipaddress>.xyz_<ipaddress>.SKIP

Example.
server_load_IP100.69.82.21.IP100.69.82.81.SKIP
server_load_IP100.69.82.21.ny_IP100.69.82.81.SKIP
[download]

Detailed Status file for process (can be in below formats)

server_load_<ipaddress>.<ipaddress>.xyx_ABC-2.SKIP
server_load_<ipaddress>.ny_<ipaddress>.ABC_load.SKIP

Example

server_load_IP100.69.82.21.IP100.69.82.81.ny_AMER-2.SKIP
server_load_IP100.69.82.21.ny_IP100.69.82.81.AMER_load.SKIP
[download]

My regular expression SHOULD NOT match any name from HIGH-LEVEL Status file for process. only that will work for Detailed Status file for process.

Tried using Look-ahead and look-behind concepts, but not able to get my best.

#!/usr/bin/perl
use strict;
use warnings;

while (<DATA>) {

if (/^(?<!server_load_IP100.69.82.21\s).*.SKIP/) {print "Good Match ";
+}
else {"Bad Match ";}
print;
}

__DATA__
server_load_IP100.69.82.21.IP100.69.82.81.SKIP
server_load_IP100.69.82.21.IP100.69.82.81.ny_AMER-2.SKIP
[download]

Output
===============
Good Match server_load_IP100.69.82.21.IP100.69.82.81.SKIP   ==> Ideall
+y this is HIGH-LEVEL Status file for process should be "Bad Match "
Good Match server_load_IP100.69.82.21.IP100.69.82.81.ny_AMER-2.SKIP

Any thoughts or guidance please. Thanks.
