Registration Data Access Protocol (RDAP)
The Registration Data Access Protocol (RDAP) is a computer network communications protocol standardized by the Internet Engineering Task Force. Developed as a successor to WHOIS, allows users to query for Registry data (domains, contacts, hosts and Registrars) over HTTPS.

How to access the GoDaddy Registry RDAP Service
Any internet user may query the RDAP service, however responses for queries made by anonymous users may be redacted. Individuals and organisations with a legitimate interest in accessing domain name registration data may request authenticated user access to the RDAP service. To make a request for authenticated access, please visit RDDSrequest.nic.[TLD], where [TLD] represents the applicable TLD you wish to request authenticated access to.
How to use the GoDaddy Registry RDAP Service
Most GoDaddy Registry supported TLD registries will have an RDAP service on the hostname rdap.nic.[TLD], where [TLD] represents the applicable TLD you wish to query. If you find that there is no response on a registry's assumed RDAP host, it may be that the Registry Operator has not implemented an RDAP service. RDAP is an API and is intended for machine to machine interaction, as such there is no web-based interface available to submit RDAP requests at this time.
Help and FAQs
What is RDAP?
RDAP stands for Registration Data Access Protocol. It was developed by the technical community in the Internet Engineering Task Force (IETF) as a replacement for the WHOIS services. RFCs 7480, 7481, 7482, 7483, 7484, and 7485 define the behavior of RDAP.
How does RDAP differ from WHOIS?
RDAP is a HTTP-based protocol that delivers data in a standard, machine-readable JSON format. WHOIS is a text-based protocol and, as it doesn't have standardized queries and responses, the interaction with Registries can vary significantly. While Registry lookup and search services have traditionally been offered through WHOIS, it has a number of shortcomings, including the lack of a standard data model, the lack of support for internationalization and the inability to authenticate users to provide differentiated services to such classes of users.
Do I need an RDAP client?
There are a number of RDAP clients currently available for use. Whether or not you require an RDAP clients depends on your needs and intended use of the RDAP service.
What is bootstrapping?
The IANA Bootstrap Service Registry publishes bootstrap files that provide the authoritative servers to query (this is called bootstrapping) for RDAP. The IANA Bootstrap Service Registry for Domain Name Space can be found here.
What are bootstrap files?
Bootstrap files are JSON files, as defined in RFC 7484. IANA publishes these files in their Bootstrap Service Registry for the Domain Name Space, as well as the IPv4 Address Space, IPv6 Address Space and Autonomous System Number Space.
How do I make a query?
The querying format for RDAP is {Service Host}/{Query} where {Service Host} is the hostname of the Registry's RDAP service and {Query} is the query that you want to submit. For example, a domain query for domain.example against the .example RDAP service would be: rdap.nic.example/domain/domain.example
What is the ICANN Operational Profile?
The 'Operational Profile' is defined by ICANN so that all RDAP services operate on a consistent basis. Our RDAP Service implements the ICANN Operational Profile. More information can be found here.
