A DNS lookup is a free tool you can find almost everywhere in the internet. First off, know what a DNS is. DNS is short for Domain Name Service or Server. A DNS associates not just the domain name but other information related to domains or domain names. DNS can store IP address, server name, email, contacts of a computer, a server, or web page that you can access over the internet.

Next, a domain or domain name is simply a website’s identifier. It can refer to several associated meanings. A domain name is perhaps the most fundamental detail that makes up a website. Imagine having a website without a name. How will your web users view your web site? How can you even advertise a website without a name? How can one go to a specific site if he or she doesn’t know what it’s called? It’s like saying I know Prison Break is a good TV show but I don’t know which network it is being aired. Sure you can search just like how you would surf channels in your television. But if you are going to search for keywords over the internet, chances are you’ll get millions of results. It may take you months or even years to find the exact website you are looking for.

Now an IP address does it for you. It identifies a certain computer, server or webpage. However, an IP address is made up of numbers. In this case, you can compare an IP address with a mobile number. Yes, you can quickly call another mobile if you know the mobile number right? But again, if you have millions of numbers to call, will you be able to memorize all those numbers? That’s why you have a telephone or address book with a name that identifies each number. That is just the same with IP addresses and domain names.

Now that you know the basics, and you’re looking for more information about a website or computer, a DNS lookup might just be what you need. If you have the IP address or domain name of a certain computer or web server or page you want to track, a DNS lookup tool can help you. Just type in DNS lookup in any search engine and you will find millions of results all linking you to a website that offers DNS lookup or DNS search. Almost all of these sites provide free DNS lookup, reverse DNS lookup, or DNS reverse lookup; you’ll even find topics about DNS error Google search that happened years ago. If you need more information, start searching and find out what you are looking for.
