Title: Can get a bit stricter
Name: Remi Sabourin

Comment:
Closer, but these should not match: ultimate.football..com ultimate-.football.com ultimate.-football.com For a stricter regular expression, see http://regexlib.com/REDetails.aspx?regexp_id=391 I did not add all the possible top level domains since this list presents a maintenance issue. However, note that all domains are case insensitive so blah.US is a valid domain also.
