Android will always use the Private DNS servers, even when a VPN is active. NOTE: If you are using the Private DNS feature of Android (first introduced in version 9) there is no need for any of the testers below. I have a list of suggested DNS providers. For more on encrypted DNS see the Encrypted DNS topic on my Defensive Computing Checklist site. Likewise, if you have two web browsers using different DNS providers, expect them to report different results in the tests below.

If one browser is using encrypted DNS while another, on the same computing device, is not, then expect these tests to show different results in each browser. The most recent change is that web browsers can now specify their desired DNS server. We need tests like these because there are many places that DNS servers could have come from. That is, they report the DNS servers your current browser is actually using. You can check a computer or router to see what your DNS servers should be, but the pages below show what they actually are (with the tested web browser). Like food, you should not take DNS servers from a stranger. For example, they might send you to a scam copy of a website. Malicious DNS servers can do what any malicious translator can do - lie to you. Probably 99% of all communication between two computers on the Internet, starts with a call to a DNS Server to translate a computer name into an IP address. The system that translates names into the underlying numeric IP addresses is called DNS (Domain Name System) and the computers that do the translation are referred to as DNS servers.ĭNS Servers are extremely important. All communication on the Internet is based on these unique numbers, website names and computer names are just a convenience. You know this site as and its IP address is 216.92.136.14. If you don't see the lock, the website is using HTTP-and is therefore unsafe.Short Introduction to DNS (switch to a Long DNS explanation)ĭevices connected to the Internet are assigned unique numbers called IP addresses. When you're logging into a website, be sure to check the protocol. Google Chrome, for example, will show a little padlock to inform you that it's using HTTPS. Related: Does HTTPS Protect Data in Transit?īrowsers may also show an icon next to the address bar to let you know your data is encrypted. You can tell if a website uses HTTPS by looking at the URL it should start with 'HTTPS' if your connection is secure. HTTPS is typically used when you log into a website, so your information is hidden. On the flipside, HTTPS does encrypt your data. This makes HTTP dangerous to use on a public network, as you're never sure if someone is logging your data. People can snoop on what you're sending and note any private information. When you send data to a website that uses the HTTP protocol, it's sent as what's called 'plaintext.' This means there's nothing that encrypts the data between you and the target server.
