What Is the History of .biz?
The .biz domain was approved by ICANN in 2001 as part of its effort to relieve pressure on the .com namespace and offer a dedicated space for businesses. Neulevel, Inc. (a joint venture between Neustar and Melbourne IT) was originally delegated as the registry operator. In 2006, ICANN contracted Neustar as the sole operator. Neustar continued operating the registry after contract renewals in 2013 and 2020, when administrative responsibility was transferred to Registry Services, LLC under GoDaddy Registry’s service provision.
