If you connect to the internet or a private network, it all happens using the Domain Name System. If you log on to a WiFi connection with any device, you are connecting to a private network, even if it is not connected to the internet, it is still using DNS to connect. DNS translates names into Internet Protocol addresses that we call IP addresses. Host names are names of computers and hosts are things like printers, routers, servers, or even computers. Host names have a computer name and Internet Protocol address. Host’s have a host hostname and also an IP address. An IP address identifies the host that it is assigned to, for example, your smartphone.
DNS has the most awesome role of transmitting data from a domain name to an IP addresses also providing a worldwide directory service for example by assigning an Internet Protocol address to a domain name. An example of this is when a user visits a website by typing a domain name which is the same thing as a web address instead of typing an IP address to view a site. DNS also gives a website owner the ability to have more than one website on the same IP address and also gives Internet Service Providers the ability to have more than one of their customers assigned the same IP addresses. Domain Name Servers store a Name Server Record on a server at the registrar where the domain name is registered and is called an NS Record. The NS Record associates the domain name with a web server that the website files are stored on.
Internet users connect to these web servers when visiting a domain name. The domain name is connected to the web server’s from the domain name server, and the DNS is used to associate the Internet Protocol addresses of the web server and the domain name. All of these elements are DNS’s most common elements of the world wide web and private networks. DNS can be a little difficult to understand, but when you know why it was created, and what it does, it can give anyone a better understanding of why it is so important to the world wide web.
The Internet started around the year of 1969 and was called ARPAnet. ARPAnet was first started by 4 universities when they started connecting their networks together, then more networks started connecting to them and continued to grow. Between the years of 1969 and 1971 ARPAnet got so big that the network could not keep up with so many IP addresses and this was becoming a huge issue that needed a very fast solution, and the was resolved in 1983 by a very smart man named Paul Mockapetris at the University of California and is still to this day the most important element of the internet, private networks, and email. The Domain Name System was created because ARPAnet was growing so fast and required an automated system that would maintain host names, internet addresses, and protocols.
