How do I flush the DNS cache on my Orbi system?
Hello, I am running an RBR50 with FW V2.5.1.8 and I've added a pi-hole machine to my network. Now I'd like to flush the DNS cache of the Orbi system so it must fetch all entries from the pi-hole box....
As FURRYe38 mentioned, the most obvious step is to reboot the router. Orbi is built on the OpenWRT project. I found this answer about flushing the DNS cache on it: https://unix.stackexchange.com/questions/8160/how-to-clear-dns-cache-on-dd-wrt
In addition, DNS cache entries "time out". This is an internet requirement in case some resource changes IP addresses. So, no matter where Orbi got a DNS entry, it will eventually time out and the next time a device ask, it will come from the Pi-hole.
Does rebooting the RBR do this?
