Google Public DNS, our known IP addresses 8.8.8.8 and 8.8.4.4, are now able to handle queries with DNS-over-TLS. The Domain Name System (DNS) for those who do not know looks like an online phone directory for domain name conversion to IP addresses.
Why DNS-over-TLS? DNS queries were vulnerable to sniffing and spoofing if someone managed to get in between computer you and the 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, users can secure queries between their devices and Google Public DNS with DNS-over-TLS, while maintaining their privacy and integrity." said Google without mentioning the obvious:
Η company (known for data collection) of course knows which domain you visit, and of course at some point your query to the DNS server will have 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 came to the procase of the DNS-over-TLS security feature, since the DNS server 1.1.1.1 of Cloudflare uses it since April last year.
