Add support for custom DNS resolutions

[dlm31]

Having issues resolving dns names. I've declard a host named "tapo or tapo.lan", but when I try to resolve either tapo or tapo.lan I get unresolved. Trying this configuration with the original dnsmasq works, but not with this addon.

enable: true
port: 53
dns_domain: lan
upstream_servers:
  - 9.9.9.9
hosts:
  - host: tapo
    ip: 192.168.0.65
  - host: tapo.lan
    ip: 192.168.0.65

hey @dlm31 ,
which dnsmasq-dhcp version are you using? Is it 2.0.1 or a 1.xxx version?

can you confirm that you've trying to resolve the "tapo.lan" FQDN from a machine having its DNS server set to the IP address of the HomeAssistant instance hosting the dnsmasq-dhcp addon ? Typically you can run resolvectl status to verify if that's the case.

Moreover the config snippet that you provided... it does not look like a valid dnsmasq-dhcp config syntax:

• the "hosts" key does not exists
• the "dhcp_ip_address_reservations" key (the most similar one to your "hosts") should contain a YAML list with keys "mac", "name", "ip" and "link".

In other words a valid dnsmasq-dhcp config for your case would look like:

dns_server:
  enable: true
  port: 53
  dns_domain: lan
  upstream_servers:
    - 9.9.9.9
dhcp_ip_address_reservations:
  - name: tapo
    ip: 192.168.0.65
    mac: <your Tapo MAC address>

Hi,

Not exactly. All those local devices i specify under the dhcp_ip_address_reservations key, do resolve properly, when I try yo resolve their ip from anaother pc on the nerwork.

What still does not work is if I try to define oher name resolutions, or override public ones.
Example, I want the dns server to return 5.5.5.5 when asked for www.google.com.
So under the dns server settings section, some kind of key should exist to be able to define it.

Ok thanks, that's more clear now what you're asking for.
Consider that this addon is not currently exposing the full capabilities of dnsmasq... at least not yet.
I flagged this as feature request and I might be able to get there at some point in the future
