.km is the Internet country code top-level domain (ccTLD) for Comoros. Registration is available directly at second-level or under a number of sub-domains (cost of KMF30000 in most categories): Second-level registrations are subject to restrictions and local presence requirements. Third-level registrations are unrestricted in *.com.km if the name is not already registered elsewhere in .km; various category-specific restrictions apply to each of the other third-level domains. Personal name *.nom.km registrations are limited to island residents and to citizens resident abroad; various categories corresponding to the individual professions each require the applicant hold a license to practise that profession.
