What is DNS over HTTPS?
DNS over HTTPS, often called DoH, is a way of sending DNS queries over HTTPS so the DNS traffic is encrypted and harder to observe or alter in transit.
What it is
DoH is an encrypted DNS transport method. Instead of sending DNS lookups in plain text, it wraps them in HTTPS traffic.
Cloudflare explains that DoH encrypts DNS queries and responses and sends them through HTTP-based protocols.
How it works
The DNS request is sent through an HTTPS connection, often on port 443.
That means the DNS traffic is protected in a way that blends with other HTTPS traffic.
Why it matters in real life
DoH matters because plain DNS can be easier to observe or tamper with on the network path.
Encrypting DNS traffic can improve privacy and reduce some risks involving spoofing or manipulation.
Common misconceptions
A common misconception is that DoH makes a user totally anonymous. It improves DNS privacy, but it does not solve every privacy problem.
Another misconception is that DoH and DoT are identical. They are related encrypted DNS approaches, but they use different transport styles.
Related questions
What is DoH in simple terms?
It is DNS sent over HTTPS so the DNS traffic is encrypted.
Does DoH use normal HTTPS-style traffic?
Yes. It uses HTTPS transport for DNS requests.
