5.  Information Collected From Registrants -  To register a name, Registrants (through their Registrars) will be required to provide basic registration information to the Registry. The minimum required information is:

• The domain name registered;
• The IP address and corresponding names of the primary and secondary name servers for the registered name;
• The Registrar name and URL or, where appropriate, the identity of the delegated manager under whom the name is registered;
• The original creation date and term of the registration;
• The name and postal address of the domain name Registrant;
• The name, postal address, e-mail address, voice telephone number, and (where available)fax number of the name holder for the name registered;
• The name, postal address, e- mail address, voice telephone number, and (where available) fax number of the technical contact for the name registered; and
• The name, postal address, e- mail address, voice telephone number, and (where available) fax number of the administrative contact for the name registered.

In addition to the above information, Registrants will be required to provide certain additional Nexus information to their Registrars. Except where it is noted below that a registration will be rejected if information is missing, failure of a registration to satisfy the Nexus requirement will result in the name being placed upon a 30-day hold, during which time the Registrar will be notified and given the opportunity to correct the information with the Registrant. If no action is taken by the Registrar within the 30-day period, the registration will be cancelled and the name will be returned to “available” status. The registration fee will not be refunded. If, on the other hand, the Registrar is able to demonstrate compliance with the requirement and the information is corrected, the hold will be released and the name will be registered.

•  Certification that Registrant satisfies Nexus requirement – if not completed, then registration will be rejected;
• Basis for compliance (Nexus Category 1, 2, or 3) – if not completed, then registration will be rejected.
• Certification that the listed name servers are located within the United States – if not completed, then registration will be rejected.
