WHOIS Lookup

Detect "Registry Domain ID", "Domain Transfer Status", "Nameservers", and "Important Dates" related to a domain name. This website uses Registration Data Access Protocol (RDAP) to fetch all these information for you

What is WHOIS Lookup service?

This page parses the user input and extracts the domain name from it then uses https://data.iana.org/rdap/dns.json to find the primary service that is responsible for the domain suffix to provide Registration Data Access Protocol (RDAP) JSON object. Note that you can either directly enter the domain name or the complete URL. There is an offline JavaScript library that extracts the domain name from the user input even if the hostname is different from the domain name. If any additional RDAP services are also recommended by the primary service, the JSON object from all of these services is collected and then parsed to extract the WHOIS data. This data can be used to detect the transfer status of the domain, or the current active nameservers. It is also possible to find the important dates related to the domain such as expiration date. Note that this web service only connects to the primary and all alternative RDAP services that are responsible for the domain suffix. No other online service is involved to display the data. Since multiple services are used to collect the data, usually you can get the most comprehensive information compared to the other similar services.

Also note that Registration Data Access Protocol is not yet available for all the known domain suffixes. If there is no supported primary RDAP service in the rdap/dns.json file, you will get a warning that this suffix is not supported. Since this page uses the real-time DNS object, all the currently supported suffixes are covered.
