I finally got around to setting up pihole on my pi (yay!). However, I have a couple of questions about configuring my router.
According to this, I should set my router’s LAN dns to the pihole. I should not set a secondary DNS. What happens if the Pi goes down? Don’t I need to set a secondary for that? I’ve seen lots of contradicting advice stating I one should set a secondary dns exactly for this reason.
Question 1 is kinda moot for me. It appears my router only allows me to set a single dns in the lan settings. When I refresh ipconfig on my windows box, I do get 2 dns entries. The first is the pihole, the second is the router. Is this ok, or might this cause some type of circular or other problems?
