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
Does this just use an upstream dns server or can it do recursive resolution like unbound? Does it cache results?
If you mean CNAME flattening I have an issue for it. If you mean recursively resolving CNAME until the end record is found, it does support it.
For example, if you set a custom record
mygoogle.lol IN CNAME google.comLeng will return a response with an A record with agoogle.comIP address when you visitmygoogle.lolI’m basically just wondering if I can replace my blocky+unbound setup with just leng!
I think the answer is yes (as leng is recursive) but can you explain your use-case and expected behaviour a bit so I can get a better idea of what you want unbound to do that blocky is not doing?
