Google Public DNS (220.127.116.11) now officially supports DNS-over-TLS that provides complete privacy for users and their search queries between their devices and Google Public DNS.
DNS allows to convert Internet domain names like www.gbhackers.com into IP addresses, in this case, un protect users queries exposed the sensitive information.
New Implementation of DNS-over-TLS now supports Google Public DNS that helps users to perform a secure query and it will be completely transmitted via the encrypted channel.
Google Public DNS launched almost 8 years ago Since then Google now implemented DNS-over-TLS protocol mission in order to provide better privacy and security.
This will completely improve the privacy and security between clients and resolvers that protect from eavesdropping and spoofing attacks.
Traditional DNS queries and responses are sent over UDP or TCP without encryption which is vulnerable to eavesdropping and spoofing but this new
Google Public DNS over TLS-encrypted TCP connections as specified by RFC 7858
So users now can secure their connections to Google Public DNS with TLS, the same technology that protects their HTTPS web connections.
According to Google, “We implemented the DNS-over-TLS specification along with the RFC 7766 recommendations to minimize the overhead of using TLS. These include support for TLS 1.3 (for faster connections and improved security), TCP fast open, and pipelining of multiple queries and out-of-order responses over a single connection. “
