Choose upstreams based on domain

[caraar12345]

Heyo,

I have a split-brain DNS set up at home, with internal homelab domains using PowerDNS as a single source of truth alongside DHCP-specific domains. So for example, [hostname].home.internal, [hostname].guest.internal, [hostname].iot.internal all go through my router's default DHCP/dnsmasq setup (dynamic), and then [hostname].srv.internal goes to PowerDNS - so more static.

It'd be awesome if I could match the same set up with leng, as the NextDNS client I currently use doesn't support any more advanced metrics than "100 domains in cache" - and I'd love to be able to see timings etc so I can debug network issues.

dnsmasq's syntax, for example, is server=/home.internal/192.168.1.1, where *.home.internal is resolved by 192.168.1.1.

Hey!

Just to make sure I understood correctly, is your need about forwarding subdomains to different upstream DNS servers? For example

• *.home.internal -> to server 1.1.1.1
• *.srv.internal -> to server 2.2.2.2

additionally, would using leng as one of your upstreams in dnsmasq solve this? Or, conversely, have the leng upstream be your DHCP server.

Alternatively, if you are splitting DNS requests per domain to different servers, that tells me you want different logic for different subdomains. If you describe what exactly you are doing, that could help. What are you using dnsmasq and PowerDNS for?
