Use the WhoIs Lookup to get owner information of a domain.

WhoIs IP Address Lookup

Enter the IP address to perform a WhoIs lookup. If you don’t know the IP address, enter the domain name. The WhoIs tool will find the IP address associated with the domain you enter and display the results below. The results will return all data currently registered with American Registry for Internet Numbers, also known as “ARIN”. Results usually include owner information, contact information, registrar, hosting provider, and name servers. To learn more information about WhoIs data, read the information below.

How the WhoIs Lookup Works

The WhoIs Lookup searches a large database to find out if the domain exists. This database is managed by the Internet Corporation of Assigned Names and Numbers (ICANN) and contains the information for every registered domain on the Internet. ICANN actually requires all domain registrars to submit owner information when any domain name is registered. To find out the owner of a particular domain name, just type the domain name into the WhoIs Lookup Tool above.

Domain Name Privacy

Since registrars are forced to submit owner information to ICANN, the owner and contact information that you use to register the domain is publicly available. All WhoIs information sent to ICANN must include the following:

  1. The registrar where the domain name was registered (i.e. GoDaddy).
  2. The owner’s name, address, phone number, and email address, the name servers.
  3. The authoritative name servers responsible for DNS.
  4. The day the domain name was registered.
  5. The day the domain name is scheduled to expire.

Essentially, privacy is not guaranteed when it comes to domain name ownership. However, many registrars and other businesses offer additional “security” or privacy for your domain name registration information. This service is usually referred to as private domain registration. For example, if you simply didn’t want someone to know you owned a specific domain or wanted to keep your personal contact information confidential, you may want to elect for these services.

How does Private Domain Registration Work?

When you register for a domain name, if you want to enroll in private domain registration, there’s probably an additional fee. As we mentioned earlier, all registrars must send owner information to ICANN. However, for private registrants, a company essentially “purchases” your domain on your behalf. The information sent to ICANN only includes the information that belongs to the private registration company, instead of your personal information. So, in the end, when a person searches WhoIs for a particular domain, they are guaranteed to get results. Part of your agreement should include the clause stating your rightful ownership of the domain. This keeps you from being wrongly stripped of your personal property.
