The domain name net is a generic top-level domain (gTLD) used in the Domain Name System of the Internet.

Verisign, the operator of after acquiring Network Solutions, held an operations contract that expired on 30 June 2005. ICANN, the organization responsible for domain management, sought proposals from organizations to operate the domain upon expiration of the contract. Verisign regained the contract bid, and secured its control over the registry for another six years. On 30 June 2011, the contract with Verisign was automatically renewed for another six years. This is because of a resolution approved by the ICANN board, which states that renewal will be automatic as long as Verisign meets certain ICANN requirements.
Registrations are processed via accredited registrars and internationalized domain names are also accepted.
