regex matching

[Brian . T . Wallace]

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..
