Domain Lookup offers 2 free tools with no sign-up to retrieve public information. Domain Whois checks the public data of a domain, for example to understand who it is linked to or when it was created. IP address Whois examines the registry and network of an address. These pages help webmasters, providers and curious users checking a domain before a purchase, an audit or a diagnosis.
The two tools differ by their starting point. If you begin with a domain name, use Domain Whois to view the public information associated with it.
