How Deep Packet Filter works (the DNS layer)

DPF operates at the DNS layer — the system that turns website and service names into network addresses. When a device tries to reach an advert server, tracker or malicious domain, DPF simply refuses to resolve it, so the connection is never made.

Getting protected takes four steps:

1. Choose a plan and complete your order.
2. Receive your primary and secondary DPF DNS server addresses by email (via your access ticket).
3. Change the DNS settings on your device, router or DHCP server to those addresses.
4. Protection is active immediately — no reboot, no app, and no configuration beyond the DNS change.

Set it on your router and every device behind it is covered automatically. There is nothing to install on individual devices.
