"Domain Name Registration Data Lookup (WHOIS)" This tool is meant to ease the retrieval of domain name meta data. The extension uses the Registration Data Access Protocol (RDAP) to fetch free information regarding the domain that belongs to the currently active tab. This data is mainly returned by rdap.verisign.com and rdap.markmonitor.com RDAP services. This extension also fetches all possible alternative RDAP services that these two primary services suggest only if the data is not protected by CORS. The extension displays the registered name domain id and the current transfer status of the domain. Also, you can find the current expiration and creation dates for this domain as well as the active nameservers. If you would like to check another domain, simply enter the name of the domain or a URL inside the domain in the search box and press the enter key.

Features

  1. What is the "Domain Name Registration Data Lookup (WHOIS)" add-on and how can I use it?

    This is a lightweight developer and security tool to get important information regarding the domain that belongs to the currently active tab. The information that is provided by this extension can be used to find fake domains and also it can be used by developers to find opportunities for finding domains that may expire soon. Also, the public contact information of the domain (Registrar, Technical, Administrative, and Abuse contacts) is displayed if the contact details are publicly available. This extension also displays the nameservers that the domain currently uses as well as the transfer status of the domain. These data could help developers find possible issues with the domain. Note that although the extension displays the domain info of the active tab, you can still use the search box to find the information of any arbitrary domain as long as the domain suffix is supported by the icann.org DNS list.

    Please check the Logs section.

  4. Why do I sometimes get "*" suffix is not supported error message?

    This extension uses the official DNS list from icann.org to find the primary RDAP server to fetch the domain data. If the suffix that belongs to the domain name in the query is not listed, the extension cannot set the service and hence you will get the error. If you are aware of an RDAP service that is responsible for this domain suffix, please report in the review section of this page and I'll update the library to support the suffix.

  5. How does this extension collect this information?

    This extension uses an offline version of the DNS JSON object that is provided by the icann.org service to provide primary services responsible for the domain suffixes. If the responsible service is detected, then the domain metadata is fetched from the service. If the returned data also suggests alternative services, the extension connects each service and appends the metadata object to a list. When all services are fetched, the required information is gathered from these metadata objects.
