I read a tweet of John Carmack (https://twitter.com/ID_AA_Carmack/status/1562104562219196416) and decided to do something similar for us.

Our network setup is pretty basic: half of the devices connect to a router and the other half connect to an wifi extender. There is no pi-hole or other middleman but I can setup if needed. I have two Pis.

Nevertheless I Googled a bit and found out about OpenDNS. I'm wondering if I can do the following:

1. Every device should have a whitelist or a blacklist

2. I should be able to upload these lists easily

3. OpenDNS does not slow down my network by much

Additionally, a good to have:

4. I should be able to setup a default policy (most likely a whitelist) for any new device that connects to the router

I appreciate all comments, thanks!
