About Us RDAP Service

The Registration Data Access Protocol (RDAP) is a standard protocol defined by the Internet Engineering Task Force (IETF) to replace the WHOIS Protocol. The RDAP is a data obtaining service for the Internet resources such as Domains, Contacts, Hosts, Registrars via HTTPS for higher level of security. In addition, RDAP is designed for more convenience by reply any query with JSON format which enabled machine- to-machine operation. More information could be found from https://www.icann.org/rdap.

Help and FAQs
  1. 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 and 7484 define the behavior of RDAP.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
  6. 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 nic.scb against the .scb RDAP service would be: rdap.nic.scb/domain/nic.scb
  7. What is the ICANN Operational Profile?
    The 'Operational Profile' is defined by ICANN so that all RDAP services operate on a consistent basis. ThaiNS's RDAP Service implements the ICANN Operational Profile. More information.
