SOA Spamming DNS Server - Conditional Forwarding

[snakedog116]

Typically what happens is someone sets Conditional Forwarding to a router that doesn’t know the answers the the requests. They also set the router to use Pi-hole for it’s queries. So a client requests host.domain , Pi-hole sends that to the router, the router doesn’t know and sends it to it’s upstream (Pi-hole). Pi-hole doesn’t know so it sends it to the router, and we have a big loop that floods everything until all the available electrons are used and the whole thing goes boom.

Here's what is says on the admin portal. That basically describes exactly what I'm trying to do... make Pi-Hole recognize the DHCP names instead of just IP addresses.

Conditional Forwarding

If not configured as your DHCP server, Pi-hole won't be able to determine the names of devices on your local network. As a result, tables such as Top Clients will only show IP addresses.

One solution for this is to configure Pi-hole to forward these requests to your DHCP server (most likely your router), but only for devices on your home network. To configure this we will need to know the IP address of your DHCP server and the name of your local network.

Note: The local domain name must match the domain name specified in your DHCP server, likely found within the DHCP settings.
