|A domain name server, also known as DNS server or IP address, is the main component of the Domain Name System (DNS). This part of the system maintains a record of every domain name registered on the Internet. It maps the IP address of one computer to the numeric representation of that domain name on a web browser. The DNS system translates the domain name to its IP address.|
A DNS server translates a domain name to an IP address. There are multiple name servers which are connected to by means of a connection such as a network cable or a Wide Area Network (WAN). There are also name servers which are connected internally. Most companies register their domain names with an ICANN, or International Certificate Of Organization. This International Certificate Of Organization is issued by the Internet Corporation for Assigned Names and Numbers (ICANN).
In addition to name servers, there are also other components which are required for a complete DNS system. For example, a Reverse Lookup service identifies name-based queries and submits the results to a centralized database. There are name lists which contain both public and private information. Some name servers are designed to support a large number of zones while some only support one or two zones.
A zone transfer allows users to move a zone from one domain name servers to another. Two common ways to transfer a zone include through a process called dynamic DNS or through a static name server. The dynamic DNS transfers the zone to the new name server while the static name server transfers the zone to the former name server. Another method by which the domain name servers are used is to provide a mail transfer agent (MTA) which can be configured by the administrator to deliver messages in a specified directory.
Apart from DNS server, there are also other important components required for a website. One of these important components is the nameserver. A nameserver is responsible for translating domain name into a meaningful numerical address and/or name. Nameservers come in two forms, physical and virtual. For virtual nameservers, it is necessary to configure each IP address manually while physical nameservers come with pre-configured settings which makes them easier to use.
When choosing a domain name server, there are several factors to consider. It is possible that the customer can not have his own server and prefers to lease one from the supplier. This is known as unmanaged domain name hosting where the web host rents out a server on which to operate. Another factor is the availability of a quality nameserver. Some suppliers offer only partial service and some provide only virtual nameservers. Customers who are looking for more reliable services should therefore consider buying their own domain name server.
When customers choose to rent their own name servers, they usually require two types of them - physical and virtual. Physical servers are more reliable than virtual ones because they are directly attached to the main Internet connection. Virtual name servers can be easily moved around the world without any significant disruptions to the network. The physical type of name server can also be included in the reselling packages. Therefore, when buying a domain name server, it is necessary to check the total cost of both physical and virtual versions.
In addition, some companies that offer domain name servers also include billing system software in the package deal. Customers should therefore make sure that they will be able to install the billing software on their own. These aspects are important aspects to consider when choosing a domain name server.
