Re: "You need a Pi-Hole on your network."
I run Pi-Hole on my network, and tbh the only problem I've found with it - and it's a big one - is that the online "what's currently on tap" page of my local pub's website doesn't work when Pi-Hole is active, and I have to drop off my wifi onto cellular to see if it's worth my wandering down to pick up a growler(*) of anything.
*Note to Rightpondians - this is a glass/metal/thermos-type 64oz beer container. For some reason my brother in the UK sniggers uncontrollably when I mention the term. I remain innocently puzzled as to why.
