I run a personal dnsmasq just for dns resolving/routing. It integrates well with Networkmanager. Easy to work with and very reliable to have the DNS resolution and routing be handled by dnsmasq. Single command to reload NetworkManager which also reloads the integrated dnsmasq. I like it and it offers a lot of control for me. I hate having to use the hosts file for when I am connecting to labs via VPN with their own network. dnsmasq is way better at handling subdomains than the hosts file and it feels way more reliable than just hoping the minimal DNS routing system works properly.
I usually ask AI to summarize it and then I get a pretty good idea of what it was meant to do. It’s just another tool to me. AI generated code sucks but it’s nice when it’s a quick summary.
