[? music ?] [DNS Basics with Jason Seifer]
DNS stands for domain name system and it's what powers the internet.
You've probably interacted with DNS before
without even knowing it.
You can think of DNS as sort of like a phonebook
translating names into numbers.
Only in the case of DNS the numbers are IP addresses,
and the names are domain names.
An IP address will usually correspond to a device on the network.
The network can either be the local network
or the internet.
When you go to a website like www.teamtreehouse.com
it's being translated into a number.
DNS is the protocol that's doing the translation.
In this course we're going to learn all about DNS and how it works.
So let's go ahead and get started.
