When do you perform a Whois domain lookup?
When you perform a Whois lookup for a domain name, it is mainly done to find out who the registrant is. This is important for domain registrants when they are dealing with the use and misuse of a chosen domain name. It is mainly used in the following cases:
- want to take over an existing .nl domain
- revealing misuse of trademark or trade name in a domain name
- request permission to use a similar domain name
