ICM Registry LLC (.xxx)

.xxx is a sponsored top-level domain for adult entertainment content. It is operated by ICM Registry LLC, which manages registration and policy for the namespace. The domain is restricted: only verified members of the adult industry may register a .xxx address. This includes producers, distributors, and performers of adult media. The domain was created as a voluntary, self-selected space to help label and organize adult material on the internet. It went into the root zone in April 2011. Registration is handled through ICANN accredited registrars. The domain has been subject to debate since its proposal, with some seeing it as a way to protect minors and others criticizing its mandatory use for existing adult sites.

The .xxx domain was proposed as early as the 2000s. ICANN approved it in 2011 after a long and contentious process. ICM Registry won the contract to run the namespace. The launch included a sunrise period for trademark holders and a land rush for qualified applicants.
