finding if an ip is in a subnetby AltGrendel (Acolyte)
|on Mar 05, 2014 at 15:58 UTC||Need Help??|
AltGrendel has asked for the wisdom of the Perl Monks concerning the following question:
This is frustrating. I have one file with a list of arbitrary source IP addresses. In another file I have subnet,netmask,dest-hostname for that subnet. I need to find a quick way to find out if that IP is in a particular subnet. I was thinking that something like this would help, but there are over 4500 ip addresses and 1500 subnets to go through.
Please note. I have some severe limitations with this.
1) This is running on a Solaris 5.8 box, perl version is 5.005_03
2) I do not have root access.
3) I do not have access to CPAN.
4) Only core modules are installed.
Any help/suggestions would be appreciated.
