Registration Data Access Protocol (RDAP)

rdapThe Registration Data Access Protocol (RDAP) was designed by the Weirds Working Group of the Internet Engineering Task Force as a successor to the  WHOIS protocol.

RDAP provides a way to query registration data using a RESTful web service and uniform query patterns. The  service is implemented using the Hypertext Transfer Protocol (HTTP)

AFRINIC has an RDAP service available at https://rdap.afrinic.net/rdap

 

The RDAP protocol addresses the deficiencies with the WHOIS protocol that have been identified over time such as

  • Lack of standardised command structures
  • Lack of standardised output and error structures
  • Lack of support for Internationalization and localization
  • Lack of support for user identification, authentication and access control

 

The AFRINIC RDAP provides users with an interface to query the following

  • Network information by IP Address
  • AS numbers by autnum
  • Reverse DNS records by the domain
  • Entities (such as persons, roles, organization) by identifier
