Whois Lookup. Discover who owns a domain and check availability.
# What is a WHOIS domain lookup?
Whenever a domain name is registered, the International Corporation for Assigned Names and Numbers (ICANN) requires that registrants provide up-to-date contact information to their domain registrars. A WHOIS domain lookup allows you to trace the ownership and tenure of a domain name.
# Will all available data be visible?
Info stored in the WHOIS database may or may not be published, based on user and registry settings. If the data you are seeking is not visible in response to your lookup request, it may not be available or you should see a remark and/or redacted label in the corresponding result field for privacy protection.
# How do I use the WHOIS lookup tool?
To use this WHOIS lookup tool, just enter the domain name (currently do not support IDN) into the search bar above. You can also use this tool to lookup an IPv4 or IPv6 address' ASN information.
