domain names

In the early days of the Internet, an IP (Internet Protocol) address (that number thingy that looks like this; 123.45.678.90) was used to locate documents on the Internet. Obviously, this was not practical in a universal approach, as people would have a hard time remembering IP addresses, so in 1984, the DNS (Domain Name System) was created. This makes it much easier to locate by its domain name instead of its IP address.
