Recursive Resolver EXPOSED | WHO Is Doing DNS Lookups for You?

Описание: When you type a website like google.com,
who actually talks to root servers, TLD servers, and authoritative DNS?

Is it:

Your laptop?

Your router?

Your ISP?

Google DNS?

Someone else?

🤯 The answer surprises most people.

In this video, we break down Recursive DNS Resolvers — the hidden workers that perform the entire DNS lookup process on your behalf.

🔍 In this video, you’ll understand:

✔ What a Recursive DNS Resolver really is
✔ Why your laptop never talks to root or TLD servers
✔ Who usually runs recursive resolvers (ISP vs Google vs Cloudflare)
✔ Why your router is NOT a real recursive resolver
✔ How DHCP secretly assigns your DNS resolver
✔ Where recursive resolvers physically live
✔ How caching makes DNS insanely fast
✔ Difference between Recursive vs Authoritative DNS
✔ Why ISPs can see DNS traffic unless encrypted
✔ When and why people switch to 8.8.8.8 or 1.1.1.1

By the end, you’ll know exactly who is resolving DNS for YOU right now.

0:00 Concept: Recursive resolvers perform a full DNS lookup on behalf of the user.
1:30 Process: Resolvers query root, TLD, and authoritative servers sequentially to find an IP.
3:00 Broker: The resolver acts as a middleman that retrieves, caches, and returns the response to you.
4:00 Source: ISPs provide DNS resolver information via DHCP alongside IP and gateway data.
5:00 Verification: Running `ipconfig /all` in the command prompt identifies your current DNS recursive resolvers.
6:00 Limitation: A home router typically acts as a forwarder rather than a full recursive resolver.
7:00 Customization: Users can switch to providers like Google or Cloudflare for improved speed and caching.
8:30 Policy: Changing resolvers can bypass ISP-level censorship and government-imposed site blocks.
10:00 Enterprise: Companies use domain controllers to block malware and log internal network activity.
12:00 Stability: Outages at major data centers can bring down the internet by preventing IP resolution.
