An Internet Protocol or IP address is different from a domain. The IP address is a real series of numeric instructions. Precise information about the address will be useful for the computer, but it does not make sense to people. The domain acts as a link to the IP address. The links do not contain real information, but they point to where the IP address information is located. It is useful to think of IP addresses as real code and domain names as an alias for this code. A typical IP address looks like a number sequence. However, people can not understand or use this code. To summarize, the domain name is part of the URL pointing to the IP address.
