Google Public DNS servers that sit at IP addresses 8.8.8.8
and 8.8.4.4, are now able to handle the more secure DNS-over-TLS specification.
Domain Name System (DNS) is the distributed, phone book-like method for
converting domain names into IP addresses.
Google
announced that their public Domain Name System (DNS) service now comes with
support for the DNS-over-TLS security protocol which wraps DNS queries and
answers using the Transport Layer Security (TLS) protocol.
“Starting today, users can secure queries between their
devices and Google Public DNS with DNS-over-TLS, preserving their privacy and
integrity,” the company wrote in a blog post. “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.”
DNS resolvers are the ones working restlessly in the
background to convert domain names such as Techunzipped.com to their
corresponding IP address the web browsers use to connect to that specific
website’s web server.
According to Google’s announcement, DNS-over-TLS is
available for Android 9 Pie users starting today.
Android 9 (Pie) device users can use DNS-over-TLS today. For
configuration instructions for Android and other systems, please see the
documentation. Advanced Linux users can use the stubby resolver from
dnsprivacy.org to talk to Google’s DNS-over-TLS service.
