WHOIS is a query and response protocol that is widely used for querying databases that store the registered users or assignees of an Internet resource, such as a domain name, an IP address block or an autonomous system.
WHOIS is also the name of the command-line utility on most UNIX systems used to make WHOIS protocol queries.
The Internet Corporation for Assigned Names and Numbers (ICANN) is the organization which regulates domain name registration and ownership.

RIPE is a Database wich contains registration details of IP addresses and AS numbers originally allocated by the RIPE NCC. It shows the organisations that hold the resources, where the allocations were made, and contact details for the networks.

• A WHOIS Lookup is necessary to find out domain name availability
• A WHOIS/RIPE Lookup is also used to find domain or IP address ownership and contact information.

• Open the Online WHOIS Lookup Tool
• Enter a domain or an IP address in the space provided (Both IPv4 and IPv6 addresses are supported)
• Click on the "Whois Lookup" button

The WHOIS Lookup Tool will then search and find domain or IP address ownership and contact information and gives you the result.

Most Linux systems include a default, basic WHOIS Client for communicating with the WHOIS Server on port 43, which stores and delivers database content in a human-readable format.
This client is available through the command-line utility: whois
For a domain Lookup: whois [domain] (Ex: whois google.com)
For an IPv4 Address Lookup: whois [IPv4Address]
For an IPv6 Address Lookup: whois [IPv6Address]
