What exactly is Whois?

Whois is a TCP based lookup tool that uses a protocol over port 43 to lookup and retrieve data of a domain name or IP address with searching and checking worldwide Whois databases. With our WhoIs Lookup tool we can search, check and obtain information on an any IP address or a domain name. Whois search protocol in essence is used for the access to public BD (the remote bases of data) of registrars IP addresses and registrars of domain names. The databases, which have whois interface, are centralized and distributed.
We search for more informations about domain names or IP address by using help from:

  • APNIC (Asian database)
  • ARIN (North American databases)
  • LACNIC (latin America and Caribbean database and internet addresses registry)
  • AFRINIC (African Information Center and registry for Africa)
