Bulk Whois Search
The bulk whois checker allows to research whois records for multiple domains at a time.
Whois is a publicly available service allowing to identify the registrant / owner of a domain name as well as the registrar of a domain. The bulk whois checker will return the domain registration info for the submitted domains.
Whois lookup results may vary depending on the type of top level domain ("TLD"). They usually include the registrant or owner of a domain name including name, address, company name and contact information like telephone number and email address. Further, whois records show the registrar of a domain name. This is the service provider used by the registrant to register the domain. Usually this is also where the website for a domain name is hosted although a registrant might use different providers for domain registration and website hosting.
If you want to find out if domain names are taken or available for registration, please check out the bulk domain availability checker.

FAQ - Bulk Whois Search
Which top level domains are supported?The bulk whois search supports hundreds of the most common domain extensions TLD, top level domain. Also for many of the new generic top level domains a whois lookup can be performed as well.
Why is there no registrant information for the domain name I looked up?Whois results may vary between domain extensions. Not all registries (operators of top level domains) disclose the same level of information in their whois databases. For some top level domains all registrant information like name, address and email address are publicly available while for other domain extensions you might only be able to check if a domain is registered or not.
Private registrations may also be responsible for missing data of the owner of a domain in whois searches. More and more domain providers offer their customers domain privacy when registering domain names. If the registrant chooses this option when buying a domain name, the registrar submits their own data to the whois instead of the actual data of the registrant.
