I believe the answer is:

dotcom

(Other definitions for dotcom that I've seen before include "Company that conducts its business on the Internet" , "Internet company (colloq.)" , "On-line business" , "Suffix often attached to website address (3.3)" , "Internet address suffix" .)

I've seen this clue in the Newsday.
