A valid IP address is going to look like four groups of one to three
digits separated by dots.
So if "one to three digits" is \d{1,3} (\d is the same as [0-9]), the
regex is going to want to look something more like
/\b\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}\b/
Notice the quoted-metacharacter dots, otherwise you'll get wacky
matches.
Now, the \b's are probably rendered moot by greediness, so unless
you are trying to avoid picking up "x12.34.56.78" you can take
those out. Someone can probably fine-tune which places don't
actually need three digits and whatnot, too.
