Custom dnsmasq

[aik]

For ages I've been using a provider's lame router and a separate orangepi with dnsmasq.
Now, I go a decent router and moving from orangepi to that thing. Mostly seamlessly, like, I "just copied" my nginx confs to /etc/nginx/conf.d/ and that was pretty much it.
dnsmasq is a problem as OpenWRT wants to control it and provides a bunch of options but some missing and I wonder what is the right way to approach this?

The things I am after and cannot spot in the WebUI are (dnsmasq with DNS+DHCP runs now on 192.168.10.200 and the router is 192.168.10.201, only DNS is served by dnsmasq):

1. hostnames instead of MAC in leases (so wifi or any of usb eth dongles - does not matter, the host provides the name and receives an IP), like:
   dhcp-host=ole,192.168.10.153,1m

2. override DNS for some servers, for example (the last line is DNS on the :
   server=/thepiratebay.net/8.8.8.8
   server=/thepiratebay.net/8.8.4.4
   server=192.168.10.201

3. I have about 80 leases, I do not really want to cut-n-paste these and I kinda like vim better anyway

I could just copy my current config over, create a service and be done with it, should I? Upgrading OpenWRT is likely to break it if I do not do it right.

1. here, there's also /etc/ethers
   
   
2. here
   
   
3. same as 1, enter one through gui, then do the rest via cli, when you've seen the syntax.

thanks! My router runs openwrt-23.05 branch git-24.264.56413-c7a3562 (too old?) so no "DNS records" (but there is "Hostnames"), cool.

oh now it turns out I cannot add leases unleeeeeess I enable active DHCP on any interface. This is annoying :-/ I was hoping I can enter all of my config and then flip the DHCP switch but I cannot.

enable DHCP for 127.0.0.1 only ?
or create a virtual interface, do the same there.

how do I do this? "lo" does not appear anywhere in the WebUI. Doing it via ssh might not produce the desired effect on the DHCP WebUI.
