.mu is the Internet country code top-level domain (ccTLD) for Mauritius. It is administered by the Mauritius Network Information Centre and registrations are processed via accredited registrars. Some registrars market it as the .music and .museum TLD.
A number of musical groups have started to use this domain, with .mu being used to indicate music. Some examples are the rock band Athlete, the country band Lonestar, the British progressive rock bands Muse and Pendragon, the New Age musical project Amethystium and the 80s influenced hardcore metal band Blessed By A Broken Heart. In addition, the UK-based record label Planet Mu also uses the .mu domain, with the .mu forming the second half of the label's name. The world's largest direct seller of musical instruments, (Musician's Friend), also uses a .mu URL (frnd.mu) as a link shortener for several of their social media channels, including Twitter. The French webpage for the Canadian Broadcasting Corporation (Radio-Canada) uses the .mu domain for its Music network's web-only personalised music streams
The Information and Communication Technologies Authority (ICTA Mauritius) published a consultation paper in September 2011 and April 2012, with a view to forcing a re-delegation. At the public consultation meeting held on 12 April 2012, an international consultant informed ICTA that their proposal was clumsy and they do not have a case for re-delegation, because their proposed model is inappropriate and will need to reach an amicable settlement with the current sponsoring organization "Internet Direct Ltd".
