Domain Name Server

Domain Name Server

1. Definition

   • A internet system which translates, stores, categorises and converts a string of letters into an IP address.
   • Example:
     • When a url is entered into the browser, it is then returned as an IP adress associated with the url

2. Advantages

   • The user doesn't need to memorize web addresses
   • Easy for the end user to use and read as instead of showing a string of numbers a DNS shows the web link
   • Remembers and categorises web addresses

3. Disadvantages

   • Could crash the whole wide web if breakdowns as there are too many root servers and backup servers targetting DNS
   • A lot of private data could end up within untrusted users
