What is a reverse lookup for a domain?
A reverse lookup refers to the method of finding out who or what is the owner of a domain name.
By looking into the WHOIS (Domain Name) database, we can find this information. The WHOIS database maintains the data and information on a domain name owner. It consists of such pieces of information as name, location, organization name, as well as various administrative contact details.
Reverse Lookup. When it comes to a company's website, we first need to decide on the domain that we are going to use for this website, so the next question that you should ask yourself is: "What domain name do I want?" If you want to have a personal blog, then you need a .blog domain.
Once we have picked the domain, we are going to enter a .COM domain and a second domain of your choice which is different from the .COM one (for example, .WEB, .MOBI, .EDU or whatever you want). If we wanted to buy a .NET domain, we would enter the .NET top-level domain.
In order to see if a domain is available, we type the domain in the address bar (or, in older browsers, by pointing the mouse on the domain name to click on it). In the URL bar we type in the extension (.com, .net, .org, .edu, .info, .be, .mobi or others) which should look like this: "Your-Domain-Name.your-domain-here.extension" for example: Google.
We can see an example of a completed Domain Lookup for Google.com: Now let's look at the results from our Domain Lookup. When we enter Google.com, we see a picture of its owner:
The last column, Status, gives us some useful information about the domain name. For example: Registrant Name, Registrar, Last Updated (in yyyy/mm/dd), Contact Person, Email, etc. Here we see some important information about the domain's owner. Google uses a Registrant Name, ie a name which appears in the WHOIS database for that domain. In the example above we see some contact details that belong to Google Inc. We can also see the date the WHOIS record was updated, what is referred to as the Last Updated Date.
