Domain Check, domain owner check, IP check and ip adress locator, search for top-level-domain information

News: In December 2017 we have updated our domain database again.
Now you can search in more than 1631 top-level domains (TLD) and second-level domains (SLD).


With our domain-check you can check, if the domain is free (available) or registered (unavailable). When the domain name is registered, the domain-checker shows you domain name information like ownership, administrative contact, technical contact and currently used nameservers (DNS).

In our search we support the country-code top-level domains (ccTLD) and country-code second-level domains, the generic top-level domains (gTLD), the new generic top-level domains (ngTLD), the sponsored top-level domains and the CentralNIC domain names.


We also have a few other domain and ip tools here. They try to assist you in:

  • lookup multiple top level domains for your search term (multi domaincheck)
  • search for information about top level-domains (top level-domain lookup)
  • lookup ip addresses (IPv4 and IPv6)
  • get your currently used ip-address (my ip address)

We wish you good luck in finding your favorite domainn name !!!
