Domain Pointing

DNS (Domain Name System) allows us to reference computers by easy-to-remember domain names, like example.com  instead of IP addresses. DNS records define which IP addresses map to which domain names and how to handle other kinds of requests a domain might receive.

To set up a domain name, you need to do two things. First, you need to purchase a domain name from a domain name registrar. Second, you need to set up DNS records for your domain by using a DNS hosting service.
