Recently there have been a couple bits of new on the DNS-over-HTTPS (DoH) and DNS-over-TLS (DoT) front.

So I feel that it is a good time to talk about the trust models inherent to the DNS query system for residential internet users and where DoH/DoT come in.

An authoritative-only name server only returns answers to queries about domain names that have been specifically configured by the administrator.
Continuing on from my theme of DNS independence, I’d like to explore the advantages and disadvantages of hosting your own authoritative name servers.
Let us take a look at my own setup for authoritative name servers.

In this post I would like to explore the concept of DNS independence by looking at two types of DNS usage that are common in our daily highly connected lives.
The two types of DNS usage:
- Recursive/Iterative DNS (first part)
- Authoritative DNS (second part)
