Fill in the query (e.g. IP, domainname, nameserver, ASN) and submit the form. The tool will try to find out which NICNAME/WHOIS server has to be queried and will send the query to that server.

If the server could not be detected, the query will be sent to the IANA server. Optionally, it is possible to enter a custom server address. In that case, the tool wil query that server instead.

Recursive queries will be made if the tool detects another NICNAME/WHOIS server in the response.
