Introduction to DNS over HTTPS

DNS over HTTPS (DoH) is a method of performing DNS queries over the HTTPS protocol, providing enhanced privacy and security.

What is DNS over HTTPS?

DNS over HTTPS is a technology that encapsulates DNS queries within the HTTPS protocol. Traditional DNS queries are transmitted in plain text, which means:

  • Network operators can see your DNS queries
  • Middlemen can intercept and tamper with DNS responses
  • Your browsing history may be recorded and analyzed

Why DoH?

The main advantages of using DoH include:

1. Privacy Protection

  • DNS queries are encrypted
  • Prevents network operators from collecting browsing data
  • Avoids DNS query monitoring

2. Security

  • Prevents DNS hijacking
  • Ensures DNS response integrity
  • Avoids man-in-the-middle attacks

3. Performance

  • Leverages HTTPS connection reuse
  • Reduces DNS query latency
  • Improves resolution efficiency

How to Get Started with DoH?

To start using DoH, you can:

  1. Use a DoH-enabled browser
  2. Configure a DoH-enabled DNS server
  3. Use DoH-enabled client tools
