LG WebOS TVs are notorious for phoning home – ads on the home screen, tracking via ACR (automatic content recognition), and telemetry across 1,700+ domains including alphonso.tv, lgsmartad.com, and various lge.com subdomains.

One domain worth blocking separately is snu.lge.com – this is responsible for the firmware update notification popups. Blocking it stops the TV from nagging you to update, which is useful if you want to stay on a specific firmware version. ...

When using Tailscale with Magic DNS enabled, hostname resolution always routes through Tailscale—even when you’re on your home network. This adds unnecessary latency for local connections. The issue is documented in GitHub issue #1227. A workaround is to use split DNS with a custom domain. Configure your local router with local DNS entries and set up public DNS entries that point to Tailscale IPs. When you’re at home, your devices use the router’s DNS. When away, they use public DNS. ...
