Arbitration cases involving allegations of cybersquatting, or improper use of trademarks in internet domain-name registrations, hit record levels last year at the two organizations that handle most of the disputes.

The National Arbitration Forum reported a 24 percent spike in new domain name dispute filings in 2010 to 2,177, up from 1,759 cases in 2009 and up 23 percent from the 1,770 cases filed in 2008.
