 | | The registry for.us domain space, administered by the Information Sciences Institute at the University of California, is currently administered as a locality based hierarchy in which second level domain space is allocated to states and U.S. territories. |
 | | Likewise, a wide range of credentialed domains are possible, i.e., domains in which the registrant warrants that it meets some standard or in which a third party authority (e.g., a trade organization, a licensing agency, a bank) certifies the identity or characteristics of the registrant. |
 | | It may be desirable to delegate such domains to a certifying entity, or to an entity that sets and maintains the standard in the case of self-certifying registrants. |
