Google Public DNS now Supports DNS-over-TLS

0

According to a recent announcement held by Google on their Security Blog, Google Public Domain Name System (DNS) now supports DNS-over-TLS security protocol which will convert the Domain Name into IP Address.

This adds extra security on the DNS search queries as the DNS queries were vulnerable of the attacks from anyone who is sitting on the wire to manipulate the DNS data with malicious contents. Now, after adding this Transport Layer Security (TLS) all the queries which pass through Google’s DNS will be changed through TLS in IP Address, which helps to reduce the threat.

“Starting today, users can secure queries between their devices and Google Public DNS with DNS-over-TLS, preserving their privacy and integrity,” Google mentioned in their 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.”

Google also added that DNS-over-TLS will be already added in Android Pie 9.0 from today itself. The users can switch over to TLS security by jumping over to their Android’ Network Setting. There they have to find Private DNS Setting and then set the DNS Provider as “dns.google.”

After the first four DNS Resolver Service Providers, Cloudflare, CleanBrowsing, Quadrant Information Security, and Quad9, Google became the fifth organization to host this service.

Now after this important step taken by Google to integrate DNS-over-TLS support, your search queries will be more secure than before. Also, all the search queries will be faster and accurate than before.
