I don't know if it's even possible. I have pihole running in a docker environment, --net host. I have a few containers on this host that's using the local pihole service. These come across as 172.x IP addresses.
Is there anyway to resolve these to the hostname using docker?
I should note, I have everything else working how I like it. It just "would be nice" to see hostnames for my 172.x ip addresses as well.
