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


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
