Namespace Registration for GoDaddy Registry EPP Extensions Namespace Identifier: gdr Version: 1 Date: 2026-03-10 Registrant: GoDaddy Registry Email: technical1®istry.godaddy Address: 100 S. Mill Ave, Suite 1600 Tempe, Arizona, 85281 USA Web URL: https://registry.godaddy/ Purpose: GoDaddy Registry is a Registry Service Provider (RSP) for Generic Top Level Domains (gTLDs) and Country Code Top Level Domains (ccTLDs). Certain TLDs have specific and special requirements which the standard Extensible Provisioning protocol (EPP) RFCs are unable to satisfy. GoDaddy Registry enables these requirements to be supported through the development of extensions that can be used by Registrars to facilitate the exchange of data between Registrar and Registry. Syntax: urn:gdr:params:xml:ns:, where is the EPP command extension. Some examples include but are not limited to: * : managing variants of internationalized domain names. * : supplying a key-value list to represent additional domain name registration details. All extensions extend the base EPP commands described in RFC 5730, according to the following syntax: extension = 1*( ALPHA / DIGIT / "-" / "." / "_" / "~") Assignment: Extensions are self-assigned by GoDaddy Registry. These extensions are designed to work only when used directly with the GoDaddy Registry Domain Name Registry System. Each extension will be unique and provide its own distinct functionality. Security and Privacy: There are no additional security considerations beyond the security model described in RFC 5730 defining the security gates with operating an EPP service for Registrar to Registry communication. Interoperability: Using the "gdr" namespace to name the GoDaddy EPP extensions ensures that they do not clash with any EPP extensions defined by other organizations. Resolution: It is not foreseen that URNs within this namespace will undergo resolution and GoDaddy Registry does not plan to operate any resolution services for "gdr" URNs.
