The DNS (Domain Name System) is the largest database in the world, holding the records of every single domain name on the planet. This database is spread out over hundreds of servers in order to ensure its continuity, and is maintained and regulated by several governmental organizations. Every time you register a domain name the records of your registration are published in the DNS, and are then sub sequentially viewable in the WHO is database, which is the publicly avoidable information of the DNS. Name servers are any web servers with DNS software, which is a type of software designed to facilitate networking and communication within the DNS system. The following information should help you understand more about the DNS and name servers in general.
Explaining the DNS
The DNS is a crucial component to the internet, and without it the web as we know it would cease to exist. The job of the DNS is to translate IP (internet Protocol) addresses, which are the numerical locations of a web site, into domain names that are easy to remember and more aesthetically pleasing. Before the DNS was developed, a web surfer would have to use an IP address in order to access a web site, which is considerably more difficult considering it is a string of numbers separated by dots. Today, computers still connect to each other sign IP addresses, however on the surface the web site visitor never has to deal with any of this because of the DNS. The domain name system also makes it easier for governmental organizations to prevent cyber terrorism and other criminal activity that could take place if all domain records were not recorded in a database.
Understanding DNS Software
DNS software, also referred to as name server software, facilitates communication between a basic web server and the domain name system. Any web server with DNS software installed can be used as a name server, and any time you purchase a web hosting plan from a hosting provider you should receive access to their name servers. It is important to note that not all web servers are compatible with DNS software so it is important to inquire about this before trying to establish your own private name servers with a particular hosting company.
Understanding Name Servers
Every web site online is associated with at least one name server, however most sites have two name servers – one for primary functions and the other for redundancy and secondary functions. The address of a name server usually appears as NS1.nameserver.com or NS2.nameserver.com, however the address s can even be the name f your own site. If you are trying to establish your own private name servers then you will need to have access to more than one IP address in your hosting plan, as well as a domain to devote to the name server, and a web server that is compatible with DNS software. You may need to seek guidance from your hosting company during the installation and implementation of DNS software.
