The internet has evolved. Traditional DNS was like sending a postcard; modern protocols are like armored trucks. Here is how they work.
The Problem: Your requests (e.g., "bank.com") are sent in plain text. Any router along the way—especially your ISP—can read, log, and even modify them.
The Solution: Your requests are wrapped in a cryptographic tunnel (TLS/HTTPS). Intermediaries only see unintelligible noise.
| Protocol | Encryption Type | Privacy Level | Best Used For... | Port |
|---|---|---|---|---|
| DoH (HTTPS) | Same as Web Traffic | High (Blends in) | Browsers, Bypassing Censorship | 443 |
| DoT (TLS) | Dedicated Secure Tunnel | High | Android, Routers, System-wide | 853 |
| DoQ (QUIC) | Next-Gen UDP Transport | High | AdGuard, Low-Latency Gaming | 853 / 784 |
DoH camouflages your DNS queries inside standard HTTPS web traffic. Because it uses port 443 (the same port used by every secure website like Google or Facebook), it is incredibly difficult for network administrators or ISPs to block or analyze.

While DoH focuses on camouflage, DoT focuses on dedicated security. It establishes a dedicated secure tunnel purely for DNS traffic on port 853. This is cleaner for network administrators to monitor (they can see that you are doing DNS, but not what you are asking), making it the preferred standard for operating systems like Android.

DoQ is the cutting edge. It discards the aging TCP standard used by DoH/DoT and uses QUIC (based on UDP). This eliminates the "Head-of-Line Blocking" problem, meaning if one packet gets lost, it doesn't hold up the rest of your data.

Packet 1 Lost -> All traffic waits
Packet 1 Lost -> Others continue immediately

Think of this as DoH upgraded with QUIC engines. It uses the same familiar HTTPS structure as DoH but runs over the lightning-fast QUIC transport layer instead of TCP. It offers the best of both worlds: the camouflage of HTTPS and the raw speed of QUIC.
