Networking

Every computer connected to the internet has an IP address, this is devised of a 32 bit number. When a user types in a web address, also known as a domain name, the command is sent to the correct DNS (domain name server). The DNS matches the domain name to to the right IP address of the website. Domain name servers are easy to use and consistent. However, with the ever increasing number of devices being able to connect to the internet, we are running out of IP addresses (which have to be unique.)
