.se is the Internet country code top-level domain (ccTLD) for Sweden (Sverige). The top domain is operated by Internetstiftelsen i Sverige (The Internet Foundation, formerly the Internet Infrastructure Foundation, and formerly branded as .SE), but domains must be registered through one of the approved registrars.
Internetstiftelsen i Sverige is managed on the basis of its charter of foundation and its statutes. The Foundation is managed by a Board of Directors, whose decisions are executed by the executive management.
I have got quite a few great .se domain names, check them out here.
