DNS or Domain Name System converts host names and internet domains to IP addresses. DNS immediately translates the words we input on the Web browser address bar to the IP addresses of Web servers that host those sites. DNS makes use of a distributed database to save this address or name information for access of the public hosts on the web. Domain Name System presumes that IP addresses do not change because it assumes that these addresses are statically allocated instead of being dynamically assigned. ISPs or Internet Service Providers have their own DNS servers and utilizes DHCP that automatically configures the IP address of the client.

When you are planning to build your own site, one of the most important things you need to have is a good domain name. And to find that will perform according to what you require, you can look for domains that are already indexed and included in directories since it will cut down the work you need to put into it should you decide to create a new domain. There are several ways to find domains already indexed or domains in directories. You can use Google to perform a preliminary search or you can use domain search services that allow you to search domains based on these categories.

Without DNS, the internet would be unable to function properly. The task that the DNS performs seamlessly and instantaneously happens and you will not even be able to see it with your naked eye. The only occasion you will think about what DNS is, is when you get an error message after you try to access a particular website. IP addresses and DNS often go hand in hand. However, even if it is possible for you to enter the IP address of the website you want to visit, it will be quite difficult on your part to memorize all IP addresses of your favorite websites. This is when DNS comes into play. It is a lot easier to enter a specific domain for a specific website because these are actually names you can easily remember.
