.mx is the Internet country code top-level domain (ccTLD) for Mexico, which in 2009 was re-opened to new registrations by NIC México. In 2009, the .mx ccTLD was rolled out in three steps:
- Sunrise period from 1 May to 31 July 2009, waiting period, registrants who have already registered any other .MX second-level domain were able to register their domain for one year
- Waiting period from 1 August to 31 August 2009, to set up the domains registered in the Sunrise period, and to resolve domain name disputes
- Initial registration period from 1 September to 31 October 2009; in this part the registration will be done with the policy first-come, first-served and only for one year with a special set of prices.
After the three phases, .mx registrations was opened to the public.
