Hello, I would like to install Pi-hole, and reading the blog, something remains unclear to me : are unbound and FTLDNS the same thing?
I read an article that refers to the installation of Unbound in parallel with pi-hole (the title says "FTLDNS and Unbound Combined", then a few months later, there is this article saying that FTLDNS which is supposed to do exactly the same as Unbound (DSN resolver) is directly integrated with pi-hole 4.0.
And since that article, I can't see no more mention of Unbound anywhere.
I probably misunderstood.
Have you just renamed the Unbound function as "FTLDNS" or are the two complementary?
How easy is to set-up both of them ?
This is not exactly true but you are surely not the first victim of the confusion about exact DNS terminology.
Let me start at the beginning: Before Pi-hole v4.0, we used dnsmasq as DNS server. Note that dnsmasq is not strictly a DNS resolver as it cannot resolve domains from the root zone down to the subdomain you want. Instead, dnsmasq should rather be described as DNS forwarder. Unbound, on the contrary is a true DNS resolver as it can do all the resolving by itself.
With Pi-hole v4.0, which features our FTLDNS server, we integrated the functionality of dnsmasq into our own engine. We actually did a bit more, but the superficial summary is that we now offer our own DNS forwarder. This offers a variety of benefits, but those are not subject of your current question, so I will skip this here.
To summarize: Unbound and FTLDNS are two separate things. They have always been separated and will always be separate.
