DNS or “Domain Name Service” is a look-up service used by every computer and mobile device using the internet. DNS converts domain names like “greycoder.com” to an IP address like “22.214.171.124”.
AdGuard DNS is a service provided by the AdGuard company. It is a free, privacy-oriented DNS resolution system that blocks tracking, ads, and phishing. You can use it instead of your current DNS provider.
Adguard DNS works like this: when a website sends a request to an ad network, the DNS sends back a “null” response. For example, when a web page looks up the domain name “ads.facebook.com” the DNS will not find that name. This means those networks request are never loaded. This is an efficient blocking method and may speed up your internet connections.
You can find instructions on changing your DNS here. I recommend changing your router’s DNS settings. This will means that all your devices will automatically make use of AdGuard DNS.
AdGuard DNS Addresses
Here are the addresses of the AdGuard servers:
Default Ad-Blocking DNS
Use these servers to block ads, tracking, and phishing:
Family Protection DNS
I also recommend using the DNSEncrypt option that AdGuard supports. DNSEncrypt ensures that your DNS requests are encrypted before they are sent to AdGuard, which protects you from eavesdropping. It also prevents DNS alteration, or more specifically:
- It guards your network against phishing attempts
- It guards against DNS Leaks and DNS Spoofing
- It helps prevent man-in-the-middle attacks
Why is the service free? Adguard says:
We will use AdGuard DNS functionality as a part of other AdGuard software, which will be distributed on a pay-to-use basis. We might also develop a paid version of AdGuard DNS based on the current one, more advanced and with more features.
