.cat Catalan This is a TLD for Web sites in the Catalan language or related to Catalan culture. Yes Yes
.com commercial This is an open TLD; any person or entity is permitted to register.

USA top-level domains

Name Entity Notes IDN DNSSEC
.edu educational The .edu TLD is limited to specific educational institutions such as, but not limited to, primary schools, middle schools, secondary schools, colleges, and universities. In the US, its usability was limited in 2001 to post-secondary institutions accredited by an agency on the list of nationally recognized accrediting agencies maintained by the United States Department of Education. This domain is therefore almost exclusively used by US colleges and universities. Some institutions that do not meet the current registration criteria have grandfathered domain names. No Yes
