Whois Lookup
Look up registration details for any domain name or IP address — registrar, important dates, name servers, network ownership and contact information, queried live from the authoritative whois servers.
What is a whois lookup?
Whois is a public directory that records who registered a domain name or who owns a block of IP addresses. A lookup returns details such as the registrar, the dates the domain was created, updated and expires, the authoritative name servers, and — where not redacted for privacy — contact information for the registrant. For IP addresses it returns the network range, owning organization and country.
