Understanding Whois lookup

Last Updated: October 23, 2023

When you register a domain name, ICANN requires that you provide personal details that include your name, address, phone number, etc. All of this information is automatically added to a publicly-available database that catalogs the owners of every domain name that is registered. This massive database of information is called Whois.

You can search the Whois database through the terminal on your computer if you’re tech savvy, or you can use any number of Whois lookup tools on the internet (such as

Understanding Whois lookup entries

When you perform a Whois search, the first thing you will see a summary similar to this one: 


Registrar: NAME.COM, INC.

Sponsoring Registrar IANA ID: 625

Whois Server:

Referral URL:

Name Server: NS1HWY.NAME.COM

Name Server: NS2CQS.NAME.COM

Name Server: NS3GXY.NAME.COM

Name Server: NS4SXY.NAME.COM

Status: clientTransferProhibited

Updated Date: 16-jun-2015

Creation Date: 31-oct-2014

Expiration Date: 31-oct-2015

This summary gives you most of the pertinent information about this domain. Obviously, the first thing you will see is the domain name itself. The next piece of information is the registrar. The registrar is the company that this domain is registered with. In this case,!

Note: Make sure not to mix up the registrar with the similar terms registrant and registry. The registrant is the legal owner of the domain who registered it. The registry is the company which manages the list of a set of domain names. The registrar acts as the middleman between the registry and the registrant.

Along with some information about the registrar for the domain, you will also see the nameservers that are on this domain. Nameservers essentially tell you where a domain’s DNS records are stored. Often, but not always, this can also indicate what company the domain is hosted with, as many people choose to keep their DNS records and hosting records together.

The next important piece of information is the domain’s status. In our example, this domain’s status is Transfer Prohibited, meaning that it cannot be transferred to a new registrar at this time. There can be a large number of statuses put on a domain depending on what is going on with the domain at any given point in time. You can refer to the ICANN website to see a full list of the statuses a domain may have.

The next three pieces of information are fairly self-explanatory: the updated date, creation date, and expiration date. The updated date is the last time a change was made to the domain’s WhoIs information. The creation date is when this domain was originally registered. The expiration date tells you how long this domain has been renewed for and when it will expire if it is not renewed again.

Below the summary shown above you will see a long list of the raw registrar data, which outlines the registrar information, as well as the contact information for the registrant, administrative, and technical contacts. The contact information lists the name, organization, physical address, phone number, and email address that was provided for these contacts when the domain was registered.
