    DNS can be hacked….use SecureDNS from Twingate to protect yourself and your people: ntck.co/twingate_zerotrust
    🔍 Your Web Browser is Dumb….without DNS🔍
    Did you know your web browser is clueless when it comes to finding websites? When you type in a URL like academy.networkchuck.com, your browser has no idea where to go. That's where DNS, the Domain Name System, steps in to save the day! 🌐
    In this video, we dive deep into the magic behind DNS. We'll break down how your browser queries DNS servers to turn website names into IP addresses, making the internet work seamlessly. From how DNS can be hacked to how you can secure your own DNS with tools like SecureDNS from TwinGate, we've got it all covered. 💻
    🔐 DNS Security Tips: Learn how to use DNS over HTTPS (DOH), DNS over TLS (DOT), and other methods to keep your browsing secure from hackers and prying eyes. Protect your privacy and keep your internet safe.
    🛠 Tools Mentioned:
    TwinGate for SecureDNS
    Raspberry Pi for DIY DNS servers
    AdGuard and PiHole for ad-blocking and DNS control
    Grab your coffee ☕, and let’s dive into how the internet really works!

    Very good summary of most of the important parts. Some time ago I actually read through the whole RFC as I implemented my own DNS server from scratch in C# :D It currently runs on my raspberry pi with mono.
    ps: SOA stands for Start Of Authority, not "State" :) Other than that all pretty accurate and comprehensive.
    pps: fun fact: in german "acid" is called "Säure" and DNA (Deoxyribonucleic acid) is actually called "DNS" in german (Desoxyribonukleinsäure). I think that's pretty fitting, the DNA of the internet :)

  • @whoacarh
    @whoacarh 3 месяца назад +23

    Sorry, Chuck, but you missed a HUGELY CRITICAL aspect. The hosts file. Before it reaches out to stub to resolve, it'll look at anything in the hosts file to see if there's a static entry. This is also a common malware/hacking method to mess with people and hack them. It's literally the first thing you should probably check to ensure it's not interfering with something in DNS (because? it's literally the first thing your device will check). If your device checks that first, you should check it first as well. There's a lot of malware out there that will bar you from even looking at your own hosts file, even though you're an admin, by the way. It's kind of a dead giveaway that your device is infected.

    I have Quad9 and security.cloudflare-dns configured using DNS over TLS setup in my router. In case 1 goes down, I have a backup. I figure this protects all devices on my network from 'known' malware. The Asus router uses normal DNS for its checks, I wish it would use the DNS over TLS. But all client traffic uses the DNS over TLS. I know this as I had NextDNS setup for awhile and that was how the traffic looked like in the logs. I also have the non-secure DNS using quad9 and security.cloudflare-dns. In my travel router, I use Cloudflare over TLS. Figure another layer of protection while in a hotel or other unknown network is a good thing.
