If you’re fed up with Meta right now, you’re not alone. Meta tracks you across millions of websites and apps and its business model relies on your data. If you want to limit Meta’s ability to collect and profit from your personal data, here’s what you need to know.
Did you set it up on your router level? I thought I’d have to set it up device by device
Not the person you asked, but also a nextdns user: I have a light (in terms of blocking) profile on my router (set up via a DoH address, but DoT and traditional DNS are also possible). Then I have a much more strict profile I use just for my phone and laptop with more serious blocking, including porn filters (recovering addict). I set these up per-device, but later I learned I can do it in Tailscale (which I did).
PiHole and AdGuard are both easy to setup servers for network wide DNS blocking. (Homenetworking)
NextDNS is an external entity that allows you to setup DNS blocking on devices that support DoT, DoH, and occasionally plaintext DNS. (For your phone and other mobile devices)
iPhones and Androids both support DoT while Firefox (and likely most modern browsers) supports DoH.
If you don’t want to rely on an external entity, you could use a wire guard split tunnel to block your ads away from your home network. Additionally you can set up a VPS and self host your DNS server there.
