Contrary to a seemingly popular misconception, DNS does not stand for Domain Name Server or Domain Name Software. DNS is an abbreviation for the aforementioned system that catalogs every domain and IP address on the internet, including registration information, as well as their relation to other domains and web hosts. The DNS is the central database of the internet, and without it, the internet would cease to exist as we know it.
IPv4 was the first standard for IP addresses. 192.168.0.1 is a common example of an IPv4 address. The most recognisable IP addresses are in the range 192.168.0.1 to 192.168.0.255 because these tend to be the ones we use at home. An IP address is a sequence of four blocks of numbers. Each of these blocks is a value between 0 and 255, which means that each block has 256 possible values. So with four blocks allowing for up 256 possible values, IPv4 allowed for around four billion unique addresses, which seemed like a huge amount.
