Awesome.

Adguard and piHole share a lot of features and I've spent time with both of them. I liked phole a lot but I have kids and one feature I liked about Adguard was that I could set up groups (so the kids get a group and essential services get another) and I could in theory just switch off internet to the kids' devices as a punishment, or even services like Fortnite or whatever.

So that's why I picked Adguard.

Now before I bought my server pc I bought an old Nighthawk router/modem on eBay specifically because I could use it to replace my ISP router that was locked down (seriously, everyone in the building uses this ISP and all the WiFi bands are the same!) I can lock devices out of the WiFi with that now if I do desire, but honestly the threat is enough so far lol.

First thing I did was send DNS to Adguard. I have run DHCP through Adguard before and it just jammed up and worked a bunch of times until I had to change it back or withstand ear bashings from my 10 year old because it kept killing his online gaming.

So as far as I can see, I don't have to use the DHCP feature to resolve the names to ip addresses, since the IP address resolves to the name via a domain name server, DNS, the Adguard, right?

I was considering .Lan but I like your .ourhome idea. We live in an old church and have The-Crypt (it was gonna be de-crypt but I changed my mind last minute) as the WiFi address so .crypt is sounding good.
