Introduction to DNS

 DNS, or “Domain Name System,” is one of the most important parts of The Internet today. DNS is essentially a server or hierarchical configuration of

servers that acts as a “phone book” for a network. DNS translates a hostname (name of a computer) to an IP address (“phone number” of a computer).


If you type in your browser, your browser doesn’t see it as words like we see it. Your browser sees the IP address, just as when you select a contact in your cellphone, your cellphone sees a phone number.


Every networked device, including webservers, phones, computers, modems, routers has an IP address. Since humans aren’t as good with numbers as

computers are, we invented DNS to translate these numbers into domain names and hostnames that make much more sense to us.
