About this tag
Technitium DNS is a self-hosted, LAN-focused DNS resolver and filtering platform discussed on WindowsForum.com mainly in the context of extending ad and tracker blocking beyond the home network. The tagged content covers using a Tailscale subnet router to advertise a Technitium resolver's private address, then setting it as the tailnet's global DNS server so Windows PCs, phones, and laptops keep using the home filter on hotel Wi-Fi, cellular, or ISP networks.
