ICANN Update: Launching RDAP; Sunsetting WHOIS

27 January 2025
---------------------------------------------------------------------

As of 28 January 2025, the Registration Data Access Protocol (RDAP)
will be the definitive source for delivering generic top-level domain
name (gTLD) registration information in place of sunsetted WHOIS
services. RDAP offers several advantages over WHOIS including support
for internationalization, secure access to data, authoritative
service discovery, and the ability to provide differentiated access
to registration data. RDAP was developed by the Internet Engineering
Task Force.

RDAP has been offered by ICANN-accredited registrars and gTLDs since
2019.

Users are encouraged to utilize ICANN's RDAP-based Lookup service at
https://lookup.icann.org/en or ICANN's open-source command-line
client hosted on GitHub. A list of other client implementations may
be found on this page.

To request access to nonpublic gTLD registration data, use the
Registration Data Request Service (RDRS) for participating registrars
or contact the sponsoring registrar directly to determine their
disclosure process. Please make sure you have first checked that the
data is unavailable through the ICANN Lookup tool. The RDRS is
intended for use by those with a legitimate interest in nonpublic
data like law enforcement, intellectual property professionals,
consumer protection advocates, cybersecurity professionals, and
government officials.

About ICANN

ICANN's mission is to help ensure a stable, secure, and unified
global Internet. To reach another person on the Internet, you need to
type an address - a name or a number - into your computer or other
device. That address must be unique so computers know where to find
each other. ICANN helps coordinate and support these unique
identifiers across the world. ICANN was formed in 1998 as a nonprofit
public benefit corporation with a community of participants from all
over the world.
