@shybry747 Thanks for the feedback!
Yes, indeed, with the IPTV, it sounds like you need to set the ISP router to bridge mode to your own router.
Your own router can then override the DNS settings for devices on your network.
Of course, there are tons of router options out there. I’ve covered DIY rack-mounted home networking routers, but I haven’t really explored the typical home router models yet.
That said, one of the best routers for a setup like that is the Flint 2 (I’ve only personally tested this one) or 3:
As far as DNS, I like using Cloudflare’s families DNS:
1.1.1.3
1.0.0.3
Those block malware and adult content/websites.
For the even higher level of malware protection (kids on your network) then a DNS provider like quad9 is outstanding:
9.9.9.9
149.112.112.112
