|A domain name server, or DNS, is the computer on the Internet where all domain name requests are handled. The domain name server is typically located on the same server as the IP address, which is the number that corresponds to the computer. Any domain name resolved by a DNS will be a dot-net name. When the DNS server receives a request, it looks up the relevant information and returns the requested information to the client.|
There are two types of domain name servers. One is a name server that works with IP addresses. These servers are called ICANN (Internet Corporation for Assigned Names and Numbers) servers. ICANN is the organization that coordinates the naming and assigning of domain names throughout the Internet. Another type of domain name server is an IP-based nameserver. An IP-based nameserver can be thought of as being similar to a telephone directory, but it searches through the Internet rather than the phone book for contact information.
All domain name servers contain a record of each domain in existence. They hold this information so that anyone can look up a domain name and find out the name, address, and other important information associated with it. When you enter a domain name into an Internet browser, the web server search the databases and returns the information requested by the browser. Some web servers search for domain name records in the WHOIS database, while others search directly in the DNS database.
It is possible for anyone to have their own domain name server. If you have registered your domain name, and you want it to be available to other people, you can request that your domain name be registered with a domain name server. If you decide to do this, you should keep in mind that you are giving up control of the domain name to the web host, so you will probably have to pay a significant fee to reserve your domain name.
The reason you would need to register your domain name with a domain name server is so that other people can find and contact you. Once you have registered your domain name, anyone can find it and send you an email. In addition, if they do not get an email from you mark that message as spam, you can block them from contacting you in the future. This makes using a domain name server an essential part of internet communications.
Another reason you might want to use domain name servers to protect your domain name is because someone might register your name and then leave you without any notice. This could happen if they found a name for your business but did not realize it was you or did not tell you it was you when you first registered your name. Without a domain name server, these people would have no way of finding your site, and you could lose customers. You might also have trouble finding a good deal if your domain name suddenly became unavailable, and you would not be able to show any offers on your site because you would have to get your name back before anyone could contact you.
One of the problems with free domain name servers is that some of them are actually bots which search all the top level domains for potential keywords and then check to see if the keyword is available. If it is not, it will check to see if it is available through another system. If it is not, it will try to buy the domain name for your name from one of the other places where you would be able to buy a domain name. While this means that your customers might not always be able to reach you and view your site, if they do need to, it will be possible for them to do so through one of the other places where you have your domain name registered. However, this type of registration often comes at a very high price.
Finally, some domain name servers are used to allow you to connect to your hosting company through a connection to the internet. When your host sees a name, they check it against a list of sites which are authoritative, or trusted, for the domain name that you want. If the name server that you want is not on their list, they will usually try to obtain it by buying it from one of the other places where you can buy a domain name. This type of registration usually costs more money than the other types of registrations.
