Every computer connected to the Internet has a unique numerical address (called an IP address) assigned to it. However, when you want to view a particular website in your browser, you don’t generally want to type in a series of numbers—you want to use the domain name of the site in question. After all, it’s much easier to remember www.somedomain.com than something like 22.214.171.124.
When you request a web page by its domain name, your Internet service provider submits that domain name to a DNS server, which tries to look up the database entry associated with the name and obtain the corresponding IP address. If it’s successful, you are connected to the site; otherwise, you receive an error.
The many DNS servers around the Internet are connected together into a network that constantly updates itself as changes are made. When DNS information for a website changes, the revised address information is propagated throughout the DNS servers of the entire Internet, typically within about 24 hours.
