The new DNS analysis

Introduction

Recently, A new DNS(Domain Name Server) that been securely safe to use in network environment. The new IP that been introduce by Cloudflare recently is 1.1.1.1. Because of that, it will make the life of the user much more easily than before.

Matthew Prince, CEO and Co-founder of Cloudflare did told to VentureBeat that

“We’re committing to, and actually having a third party come in and audit the fact that we’re destroying all of the logs within 24 hours, we’re never writing any of the source IP addresses to disk, and that’s the only personal identifiable information that would be there.”

Findings

As i was analyse the network connection using 1.1.1.1, the packets show the speed have been increased.

The tools that i’m using to analyse is WireShark

The website that i test is Google.com where the time that to upload is 0.010747000 second which is much faster compared to old DNS.

The other website that i test here is youtube.com where the speed to upload is 0.010237000 second. I did notice that youtube upload is much faster than google
