A domain name is actually a lingual representation of an IP address, which is a series of numbers separated by dots. Every web site is given an IP address, however it is more difficult to remember this segmented sequence of numbers instead of remembering a simple phrase. This is the basic concept of domain names, but the process through which an IP address is translated into a domain names is a bit more complicated.
Domain Name Server, A DNS (Domain Name System) server is a type of web server which is used to interact with the domain name system, which is the global directory of domain names and corresponding IP addresses. DNS technology automatically translates long and confusing IP address (which are segmented number sequences separated by dots, such as 127.0.0.1) into standard domain name that is easier to remember.
The domain name system is comprised of thousands of domain name servers around the world, which accumulatively make up the largest digital database on the planet. DNS servers operate using special software that transmits data from the DNS server to various web hosts upon request.
