Is it possible now via Luci to configured different DNS server per static lease?

2

At least it's possible via uci or direct file changes to /etc/config/network.

No. You should really get familiar with SSH/UCI/file changes. It's really easy once you do it a few times.

When I try to add list dhcp_option '6,94.140.14.15,94.140.14.16' it doesn't get assigned to the host

config host
option mac '80:32:53:38:AB:E4'
option name 'SomePC'
option dns '1'
option ip '192.168.1.5'
list dhcp_option '6,94.140.14.15,94.140.14.16'

Can you try

list dhcp_option '6,94.140.14.15'
list dhcp_option '6,94.140.14.16'

Then you need to restart the dnsmasq service

/etc/init.d/dnsmasq restart

Edit:
Actually after looking at
https://openwrt.org/docs/guide-user/base-system/dhcp_configuration#providing_custom_dns_with_dhcp

It looks as though the way you set it might be correct. Did you restart dnsmasq after making the change?

6

Yes I restarted the dnsmasq, will try to separate line by line.

it gives this DHCP

Is this with 2 separate lines? Can you try it with a single DNS server please?

list dhcp_option '6,94.140.14.15'

Are you able to check the logs to see if there are any errors after restarting dnsmasq / when the DHCP lease happens.

There is a specific way to set individual options.

config tag 'custom_dns'
        option dhcp_option '6,94.140.14.15,94.140.14.16'

config host
	    option mac '80:32:53:38:AB:E4'
	    option name 'SomePC'
	    option dns '1'
	    option ip '192.168.1.5'
	    option tag 'custom_dns'

You have set a static lease of 192.168.1.5 so it looks like this is not the pc you have set a static lease for, i.e the mac address is not corresponding

it is just a sample of my other hosts
