Most websites have a domain name. In fact it would be very difficult these days to find any website that doesn’t.
Every website lives at its own unique address called an IP address. Google’s IP address is 220.127.116.11. Go ahead and try typing that into the address bar on your browser. You’ll find it opens up the Google search page.
Imagine if we had to remember the IP address for every website we wanted to visit! That’s where domain names come in. A domain name is mapped to a website IP address so instead of typing in the number you just need to remember the name, e.g. www.google.com
