Earlier today IANA added the .XXX Top Level Domain to the root nameservers. While the registry operator Afilias is still in their setup process for ICM registry, the zone is currently propagating. While a number of registrars have already been taking pre-registrations, the actual timeline for the launch has not yet been published. The Sunrise launch is a three phased approach. After much back and forth and protests against the sTLD the ICANN board had approved the application for the new TLD at their meeting on March 18th of this year.

[Update] As Kevin over at DomainIncite points out in his post on the same topic, the registry website, sex.xxx and porn.xxx (both placeholder pages, safe for work) are now resolving under the new TLD. xxx.xxx is resolving as well.

The delegation record for the new TLD can now also be found on the IANA website.

Below the output of the dig query:

dig ns xxx.
