"Domain Network System" is also known as DNS and is crucial in webhosting. With the database system of DNS, an IP address can be derived from any computer's name. This IP address is further used for computers on a network to connect and share data. However, it is a difficult task for a common man to memorise the IP address as it is a complicated series of numbers. This is why a domain name is used, since it's much easier to remember compared to memorizing a bunch of numbers.
With DNS, users can connect to other computers on the network or any other remote service with just the domain name. Any organization that hosts a computer network will have at least managing queries related to domain network system. The web hosting provider's "name server", for instance, is more commonly called the server. This server entails the list of all the IP addresses that are recognized by the network. All the IP addresses which have been accessed outside the network are also listed here.
Each computer on the network just needs to remember the location of just one name server. There are three possible outcomes when any computer connected to the network requests for an IP address. The first thing that may happen is that if the IP address which you have requested is locally registered, then you will receive a response directly from any local name servers that have been listed in your network configuration. The response is immediate. The second outcome can be that if the IP address is not registered locally but someone in your network has recently also asked for the same address, then the local name server will retrieve the requested address from its cache. For this, there is almost no waiting time at all.
Lastly, the local name server will make a search on behalf of your network. This is in case the IP address is not registered locally and you're the first person to ask for it. The local name server will have to access potentially remote servers in the process. The number of intermediary name servers as well as the speed of your Internet connection could determine the speed of the response. Sometimes there might not even be a response. If this happens you will get an error message or the query will be repeated.
Connecting to another computer using any application will usually entail you entering a domain name, instead of the long numeric IP address. The application will then look for the corresponding IP address registered on the name server from the domain name entered. The IP address can be easily retrieved as long as you know the remote computer's domain name. In many internet applications, you will not be able to see the IP address of the computer to which you are connecting.
