Ok.  (?: ... ) groups part of the regex.  It just binds it together as one
big clump.

The {3} is a quantifier, like {1,3}.  {1,3} means "1, 2, or 3 times".  {3}
means "exactly 3 times".

So (?:\d{1,3}\.){3} matches the same way that \d{1,3}\.\d{1,3}\.\d{1,3}\.
does, only it's shorter and easier to read.

Look for the chapter on regexes (in Camel III) or else look at the
'perlretut' documentation on http://www.perldoc.com/.
