Google Public DNS, our familiar IP addresses 8.8.8.8 and 8.8.4.4, are now able to handle DNS-over-TLS queries. The Domain Name System (DNS) for those who don't know is like an online phone book for converting domain names to IP addresses.
Why DNS-over-TLS? DNS queries were vulnerable to sniffing and spoofing if someone managed to get between your computer and DNS server.
But using Transport Layer Security (TLS) can make the process a bit more complicated safe as it encrypts the connections and of course the queries.
"From today, the users can secure queries between their devices and Google Public DNS with DNS-over-TLS, keeping it privacy and their integrity", said Google without mentioning the obvious:
The company (known for collecting data) naturally knows which domain you are visiting, and of course your query on the DNS server will need to be decrypted.
Users of the Android 9 version of Google have the ability to use DNS-over-TLS, as there is a Private DNS setting in Android network settings.
Let's mention that Google has come to add the DNS-over-TLS security feature, since the DNS server 1.1.1.1 of Cloudflare uses it since April last year.
