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
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?
