The oversight group for the registry of addresses on the internet is hoping a change in policy will stamp out the practice of sampling or "tasting" domain names without paying for them.

The California-based Internet Corporation for Assigned Names and Numbers, or ICANN, announced Tuesday that it was looking into closing a loophole in the process of registering domain names.

The loophole, called the Add Grace Period, allows a five-day period following the registration of a domain name during which time the registrant can cancel the registration and receive a refund.

Originally designed to allow people to rectify mistakes — such as spelling errors — the grace period has become controversial because automation allows savvy computer users to sample domain names in large numbers and keep those that might generate ad revenue — a practice called "domain tasting."

"Domain tasting has been an issue for the internet community and ICANN is offering this proposal as a way to stop tasting," Paul Twomey, ICANN's president and CEO, said in a statement. "Charging the ICANN fee as soon as a domain name is registered would close the loophole used by tasters to test a domain name's profitability for free."

ICANN says tasting has been a serious challenge for the internet community and has grown exponentially since 2004. In January 2007, the top 10 domain tasters accounted for 95 per cent of all deleted .com and .net domain names — or about 45.4 million of the total 47.8 million domain names deleted.

The oversight group still has to get the proposal approved at an ICANN board meeting in June. If it's approved, it could be implemented later this year.

Google to crack down on domain kiting

ICANN's decision comes after Google Inc. announced on Jan. 25 it would place more stringent rules on one of its advertising programs to eliminate both domain tasting and another practice, called domain kiting.

With domain kiting, registrants cancel their domain name before the grace period expires and immediately re-register it, a process that can continue indefinitely and allow a person to avoid ever paying for the domain name.

Google's new kiting detection system is to take effect on Feb. 11.
