How does CONTROLD work?CONTROL D is a fully customizable DNS service, similar to Pi-Hole, AdGuard or NextDNS, but with proxy capabilities. This means it not only blocks things (ads, porn, etc), but can also unblock websites and services.
What is DNS?Think of it like Google Maps. You type in a name of a restaurant you want to go to, and it gives you the street address of the restaurant. A DNS server does the same thing, except the street address is an IP address of the website you're trying to reach.
What is a proxy?Sticking with the food analogy, instead of going to the restaurant, you can order food through an app. A person will go get the food on your behalf and bring it to you. The restaurant has no idea who you are or where you live. A proxy does exactly that, but for websites.
