Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:
I want a quick and easy way to check if a value looks like an IP address, i'm happy just to check if the variable holds 4 numbers separated by dots.
So far I have got
if ($Route=~m/\d\.\d\.\d\.\d/) { do something interesting with the IP address }
Any better way of doing this?
Cheers,Tom
