# What is a Whois domain lookup?
As per ICANN regulations, when a domain is registered, registrants must provide registrars with up-to-date contact information. A Whois domain lookup allows you to trace the ownership and tenure of a domain name.
# Will all available data be visible?
Some available Domain Name Registration Data may be visible by only those who have demonstrated a legitimate and proportionate purpose for viewing it and have been approved to do so. 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 to indicate that there may be data available which is not visible to you.
