Every computer connected to the Internet must have a unique address, termed an IP address, in order to communicate with other computers on the Internet. IP addresses are numeric and consist of four sets of numbers, such as 128.253.242.110.

Because few people can memorize many IP addresses, we rely on "host names" and "domain names" to replace them; for example, when we want to connect to the CUinfo web site, we enter cuinfo.cornell.edu (the host name "cuinfo" followed by the domain name "cornell.edu") instead of 128.253.242.110.

Although the more meaningful names are easier for people to remember, computers need to translate these names into numeric IP addresses. To perform this translation, a personal computer contacts another computer, called a domain name system (DNS) server, which maintains a complete, up-to-date list of IP addresses and corresponding names for all of the computers on the Internet. The personal computer only needs to keep track of the IP addresses of one or more DNS servers.

Sometimes you may see a "not found" message when you enter a host name and domain name. If you are certain that you typed the names correctly, the problem could be that the host and domain names are new and have not yet been added to the DNS server's list. When this happens, you may be able to reach the computer you are trying to contact if you enter its numeric IP address instead of its host and domain names.

DNS stands for Domain Name Service.

When you type a URL, your computer passes it to a DNS server and gets back an IP Address.

IP addresses are numbers xxx.xxx.xxx.xxx, where xxx is a number between 0 and 255.

Computer networks are organized around IP addresses, not names.
