Both encrypt DNS queries. DoH hides DNS traffic inside HTTPS (harder to block). DoT uses dedicated port (easier to manage). Use DoH to bypass blocking, DoT for transparency.

DNS over HTTPS (DoH)
Encrypts DNS queries inside HTTPS traffic.
✓ Pros
Hides from ISP blocking
Looks like regular HTTPS
Supported in browsers
Bypass censorship
✗ Cons
Harder for IT to manage
Can't be filtered
Slightly more overhead
DNS over TLS (DoT)
Encrypts DNS queries using TLS on port 853.
✓ Pros
Dedicated port (easier to manage)
Slightly faster
More transparent
Network admin friendly
✗ Cons
Easier to block (port 853)
ISP can detect you're using it
The Verdict
Use DoH if you need to bypass ISP or government blocking. Use DoT if you want transparent encrypted DNS. Both protect your privacy equally.
