About ALCHosting Whois registration data lookup tool
The ALCHosting Whois registration data lookup tool gives you the ability to look up the current registration data for domain names and Internet number resources. The tool uses the Registration Data Access Protocol (RDAP) which was created as a replacement of the WHOIS (port 43) protocol. RDAP was developed by the technical community in the Internet Engineering Task Force (IETF). RDAP has several advantages over the WHOIS protocol, including more secure access to data, a standardized and user-friendly format, support for internationalization, and the ability to provide differentiated access to registration data. More information can be found here.
The registration data lookup tool conducts Registration Data Access Protocol (RDAP) queries. ​RDAP enables users to access current registration data and was created as an eventual replacement for the WHOIS protocol. The results displayed come directly from registry operators and/or registrars in real-time. ALCHosting Whois does not generate, collect, retain, or store any data associated with an RDAP compliant lookup. For domain name queries, if the queried information is not available in RDAP, the query will be redirected to the WHOIS service of the corresponding gTLD registry operator (WHOIS failover lookup). In cases of WHOIS failover lookups, ALCHosting Whois may generate, collect, retain or store the domain name queried and the results for the transitory duration necessary to show results in response to real-time queries.
