IP Addresses and Domain Names

In order to understand what the DNS is and how it works, you need to have a basic understanding of IP addresses and domain names. An IP address, or Internet Protocol address, is a complex string of numbers that acts as a binary identifier for devices across the Internet. In short, an IP address is the address that computers, servers and other devices use to identify one another online. The vast majority of IP addresses are arranged into four sets of digits – i.e., 12.34.56.78.

A domain name is the information that you enter into a web browser in order to reach a specific website. When you input a URL like www.example.com/index into a web browser, its domain name is example.com. Basically, a domain name is the human-friendly version of an IP address. Businesses vie for easy-to-remember domain names, since they make it easier for people to remember how to find them online. If people had to remember complex IP addresses in order to navigate the Internet, it wouldn’t be nearly as useful or enjoyable.
