Dedicated Domain Name Servers

What is the work of dedicated domain name servers?

A dedicated domain name server maintains a directory of domain names and their matching IP addresses. This translation enables other systems to locate and link with your system and eventually connect to your site. A central registry collects all domain names registered any where across the global internet space for the benefit of identification and subsequent redistribution at any required time. Computer networks across the world check in with this Central Registry on a regular basis to get updates about your domain and where to find your domain name or website. Computers would not know where to find your website or any other website without the information from a dedicated domain name server.

The dedicated domain name server system makes it possible to assign domain names to groups of Internet users systematically, independent of their physical location. This makes the World Wide Web (WWW), hyper links and Internet contact information to remain consistent Internet routing structures are changed. The dedicated domain name server system also distributes the responsibility of assigning domain names and mapping the same names to IP addresses. This is done by designating authoritative name servers for each domain. The authoritative name servers are in turn assigned their particular domains; this chain can extend to several sub domains thereby making the distributed Domain Name Server fault tolerant and helped in avoiding the need for a single central register

The dedicated name server is maintained by a distributed database system using the client-server model with name servers as nodes. Each domain or sub domain has one or more authoritative Domain Name Servers that publish information about that domain and the name servers of any domains subordinate to it. The top of the hierarchy is served by the root name servers: the servers to query when resolving a top-level domain name.

Dedicated domain name server hardware requirements

Dedicated domain name servers run for long periods without interruption making hardware reliability and durability extremely important. Although servers can be built from ordinary computer parts, dedicated domain name servers need to be built from specialized hardware with low failure rates in order to maximize up-time. The use of fast, high capacity hard drives and large computer fans or power supplies that ensure the servers continue to function in the event of a power failure should never be compromised. Hardware redundancy setup is highly advisable as this will ensure your system continues running even if one of the hardware happens to fail. Installing more than one instance of hard wares such as power supplies and hard disks will guarantee your system high up-time which is quite essential in the case of dedicated domain name servers. It is highly advisable to use memory devices which detect and correct errors as these will help in reducing system failures or data corruption.

Domain name software requirements

Just like any other servers, the dedicated domain name servers must have an operating system on which to run different applications. The two most prominent operating systems providers are Microsoft and Linux. The use of either of the operating systems will depend on how familiar the administrator is with ether. Other than the operating system, there are other application soft wares that are vital for the full control of your dedicated domain name server. This may include the control panel software, antivirus soft wares among others depending on the needs of each individual.

Dedicated name server storage.

After the assembly and setup of the server, it is very important to take into consideration the storage facility for the server. This is because the dedicated domain name servers store very important information and therefore need to be kept in high security environments. It is highly recommended to keep the servers under lock and key and only authorized and experienced personnel should gain access to the machine. Simple interference from an inexperienced person could lead to serious damage that could even result in the loss of useful information that has cost lots of money to compile.

Besides the tight security, the dedicated domain name server should be mounted in highly ventilated atmosphere to avoid dampness. It is also advisable to get a location with High Voltage Alternating Current to save you the inconvenience that may be caused by frequent power surges and outages.

Advantages and disadvantages of dedicated domain name servers

The greatest advantage that can be derived from the use of dedicated domain name servers is in the fact that they will save smaller companies who would wish to register domain names the opportunity to do so without having to invest in excessively expensive equipment and personnel in order to have a domain name registered. This also helps them get an online presence without having to bother about the day-to-day running and maintenance of the server. Although the use of dedicated domain name servers can prove to be very helpful by giving companies the chance to register domain names and host them at reasonable costs and with limited involvement in the day-to-day operations of the server, there could be some limitations involved in the process. Take for example the fact that the domain registered often gives limitations to the number of mail addresses available to each domain registered. There may also be inconveniences in case you need t register a mail address urgently only to realize you cannot access your system administrator as quickly as you would like to.
