leng - a fast DNS server with adblocking, built for self-hosting (github.com)

A few months ago I went on a quest for a DNS server and was dissatisfied with current maintained projects. They were either good at adblocking (Blocky, grimd...) or good at specifying custom DNS (CoreDNS...).

So I forked grimd and embarked on rewriting a good chunk of it for it to address my needs - the result is leng.

it is fast
it is small
it is easy
you can specify blocklists and it will fetch them for you
you can specify custom DNS records with proper zone file syntax (SRV records, etc)
it supports DNS-over-HTTPS so you can stay private
it is well-documented
can be deployed on systemd, docker, or Nix

I have been running it as my nameserver in a Nomad cluster since! I plan to keep maintaining and improving it, so feel free to give it a try if it also fulfils your needs

How is PiHole not built for custom DNS? It literally has an entire management page for that.

Last I used PiHole many years back, it was possible to use it as DHCP but not possible to add custom DNS records like TXT, SRV, etc. . Perhaps that’s what OP is trying to solve for?

Pinhole has allowed custom local records for a very long time now

Including SRV records? I found that some servers (blocky as well) only support very basic CNAME or A records, without being able to specify parameters like TTL, etc.

I also appreciate being able to define this in a file rather than a web UI

It's based on dnsmasq. You could always specify custom records, even before there was an option in the web interface. Just create a config file in /etc/dnsmasq.d

Just look up these options: host-record cname srv-host

Thanks! I didn't know you could do that. I'll see how it compares to my current solution

[–] [email protected] 5 points 10 months ago

I do it via dnsmasq, that Pi uses.

I have a ansible playbook, that i use to sync my Piholes.

You can do the basic records via file. /etc/pihole/custom.list is a hosts formatted file for records so you don't have to use a gui.
