Whois Lookup IP & Domain

Whois lookup (pronounced who is look up) uses the Whois protocol for obtaining information about a domain or IP address.

The Whois protocol is communication between the Whois client on the one hand and the Whois server on the other. The information request uses the standard TCP / IP protocol on port 43 where the client sends a text request to the server and this responds with the text content. The TCP connection ends when the client receives a complete response from the server that closes the connection itself after making the received request

As we can see from the above explanation, the process of obtaining an IP or domain takes place through query according to the Whois server database. The feedback contains mainly the name and contact details of the owner including the name of the provider and nameservers of the DNS servers.

The following servers are used to obtain Whois information

  • ARIN (covers Canada, USA and parts of Oceania)
  • RIPE (Europe, Middle East and Central Asia)
  • APNIC (Asia), LACNIC (South America)
  • AfriNIC (Africa)
  • IANA and RADb (worldwide)

Our Whois tool together with IP location is a very powerful and useful tool for determining location behind IP address and domain including, among other things, name and owner information.
