I recently installed myself a Pi-hole on a orangepizero with a 64gb sdcard I had laying around
I updated to the latest beta build for the NXDOMAIN blocking through FTLDNS
Everything works fine with the exception that when I try to access a PC in my network it replies with a NXDOMAIN (shown in the query log)
I can ping the IP fine but if I ping the computer name (in this case it's actually pc-name.speedport.ip) it only works with changing my DNS to not-pihole
You need to enable DHCP on Pi to be able to query using computer names, it says so on the settings page:
"Conditional Forwarding
If not configured as your DHCP server, Pi-hole won't able to determine the names of devices on your local network. As a result, tables such as Top Clients will only show IP addresses."
thought about it as a fallback solution even if i dont think that the Google or opendns Service will have any downtime at all... while they are both reacheble pi-hole uses them 50/50 (or 33/33/33)
when i look at this
perhaps its will be the best solution to use the level 3 Servers...
