Automatically Update DNS Rewrites for Local DHCP Hostnames

[Junto026]

I use AdGuardHome as my DHCP and DNS server, and I have a domain registered mydomain.com. I want to be able to associate each device in my network an IP address, it's hostname (e.g. printer.mydomain.com) and then have any device in my network be able to resolve it.

I can sort of accomplish it by creating a static DHCP record for the printer, and give it the hostname printer.mydomain.com. But the only way it resolves is if another device requests printer.mydomain.com.lan. I know I could add a second DNS re-write entry that points printer.mydomain.com back to the IP address of the printer, but that means I'd have to have 2 things configured for every device (it's DHCP entry and its DNS re-write).

Is there a way to do this without having two configurations for every device?

If I'm not completely mistaken, that can be configured in your AdGuardHome.yaml file in the dhcp secrtion.

 dhcp:
   local_domain_name: mydomain.com

That did it, thank you!! My last step is to figure out how to add a DHCP option to send the search domain to all the clients. I suspect I can figure that out through existing documentation. Thanks so much for the quick reply and I’m glad it was so simple.
