Yeah. I like to consider DNS the phone book of the internet. You know you want to talk to Google but you only know Google by name. Not their actual phone number. So your DNS server converts Google.com into 8.8.8.8 or whatever googles IP address is for you. What’s nifty is this can be used in a few ways to block/disallow certain content. And can slightly dictate the paths your connection takes on the internet.
