I have perl script written be someone else and I need to fill in the
each octal with leading zero if needed, so ip address can be sorted

This must be an very common requirement.

Is there some standard perl module I can use to perform this task?
An sample of the perl code to accomplish this would be very helpful.
The ip address is already in $src_ip
