A domain name represents a physical point on the Internet — an IP address. The Internet Corporation for Assigned Names and Numbers (ICANN) governs coordination of the links between IP addresses and domain names across the Internet. With this standardized coordination, you can find websites on the Internet by entering domain names instead of IP addresses into your Web browser.
In layman’s terms, you can type 18.104.22.168 (IP address of the host) into your browser to search the Internet or you can type in Google.com. Google.com is a domain name that points to the physical location or point on the Internet. In this case, 22.214.171.124.
