Registration Data Access Protocol (RDAP)

The Web Extensible Internet Registration Data Service Working Group (WEIRDS) is the Internet Engineering Task Force (IETF) working group responsible for defining the new method for querying the Internet registry database and thus obtaining information on IP addresses, ASNs, points of contact and organizations.

The Registration Data Access Protocol (RDAP) has been designed to address the shortcomings of the traditional whois system. This standard will allow solving issues such as internationalization, standardization, inclusion of special characters, parsing difficulties, and the inclusion of new types of queries.

The RDAP service is based on protocols developed within the framework of the Internet Engineering Task Force (IETF), to which LACNIC technicians also contributed.

RDAP has major advantages over the traditional WHOIS: it provides a standard, unified response; it's easier to use and integrate with other systems; and it allows performing queries in languages other than English.

In addition, LACNIC will introduce the use of API Keys, access tokens that will allow users to receive differentiated services once they've signed an agreement to ensure proper use of the information.

Access to the WHOIS information via RDAP is subject to the same restriction than traditional WHOIS queries. For special access -- essentially equivalent to Bulk WHOIS -- please fill the form in the following link.
