Here's a solution I sent to the group earlier...
For the array thing, have you considered using a hash instead?? How do you
know where to insert the data in the array? Is it needed after another
value, or at a certain element??

This will give you the IP only if valid. I've attached as a file too in case
the code gets mangled.

Subject: regex matching
i have a basic knowledge of regex but i want to know if there is a
simpler way to pull patterns out of a line.
if i have a line like:
here is a sample with 123.456.123.456 in the middle.
m/\d\.\d\.\d\.\d/ will match the entire line. is there an easy way to
get only the ip address?
thanks..
