|Domain nameservers are servers that act as a back-up for domain names. On the other hand, DNS server is the computer hardware that translates domain names to IP addresses. In effect, domain name servers enable users to access a web site by typing in a domain name instead of an IP address. In fact, most web browsers and software providers usually require domain name servers. In addition, some hosting providers provide domain name servers as a service.|
A domain nameserver is a server that holds a large database of different name-looking up processes. This includes look-up through a domain name registry, look-up through DNS server and search through publicly available information. The major advantage of domain nameservers is that they perform look-up with higher confidence and speed. Apart from this, domain name servers also allow users to easily register their domains in any hosting provider.
Users can register their domains online. They just need to find a suitable host that offers domain name services. Then, they submit their domains to the host so that the service provider can hold the domain name for them. After this, the host can publish or redirect the domain name to their website.
In addition, users can control the functioning of their domain name servers. They can configure DNS server to record or deny any domain name. This feature makes it easy for people and organizations to manage their domain names in an efficient manner. Users can also change or add domain names with the help of DNS servers.
Nowadays, many companies use DNS servers to support customer websites. These servers allow clients to enter domain name into the browser. When a domain name is typed, the system looks up the corresponding IP address in its server directory. If the IP address matches with the one entered, the server then returns a message to the client saying the domain name is available. This happens automatically without the knowledge or help from the user.
The role of domain name servers is further explained by programmers as being directory service. They check if a domain name is already taken. If not, the servers provide the list of available domain names to the client. They determine whether the domain name should be blocked or not. As soon as the name is available again, the directory service returns the IP address. At this point, the process is repeated to check if the domain name is still owned by the client.
In some cases, domain name servers also provide email services. They allow clients to check their email and send mail to it. These services are offered by the ISP also. However, these services are not offered by all the ISPs. The users need to check the specifications of the internet mail services to know about the availability of such a feature.
Apart from providing a means for people to find their information, name servers also play a crucial role in maintaining the integrity of the domain name system. They contain all the records about a name. Therefore, if someone tries to register a domain name which is already taken, the DNS will return true before it finds out that the owner tried to register the name. If a name server is used, then the chances of finding out that the given name is already taken reduces drastically.
Another major advantage that come with using domain name servers is the ability to make internal changes to the system without affecting any other clients. These changes can be done by changing the IP addresses, or keywords. If you use this facility, then anyone who has an account in your company cannot access your email or change their password. There are many advantages of using these domain name servers besides maintaining privacy of the domain name.
An email account can have its own security risk. An unprotected account can give hackers access to your confidential information. This is why you should only use a dedicated email server to prevent hacking into your company's confidential data. A dedicated server also provides better security because the intruder cannot just change the IP address anytime he wants. If you are planning to use a free email account, you must remember one thing - you are opening up your business to every kind of risk, and this includes the risk of hacker attacks.
If you want to protect your domain name and make sure that nobody can attack your company from any corner, then the best solution is to install a good and reliable web server. There are many free web servers available today, but they are not reliable enough to ensure your safety. When you choose a paid web host, you get a huge range of features that you can take full advantage. You will also have the added advantage of getting email support.
