After choosing the **ISP and WISP Configuration option**, you will be prompted to enter your public IP address or a public network range.

Any **public IP address** that sends DNS queries to our hosts will need to be listed and granted as a trusted **IP or network**.


We always suggest configuring both **DNS Anycast** (185.236.104.104 and 185.236.105.105) to ensure full redundancy.


We strongly suggest redirecting any outgoing **DNS requests** (**port 53 UDP and TCP**) to the secure DNS of the filter to ensure that no one tries to bypass DNS protection using third-party resolvers.


**DNS redirection** is a **simple firewall NAT** **rule** and can be easily implemented by asking the *router/gateway administrator*.


Some routers are also capable of redirecting *DNS requests through Layer 7 application control*. It is possible to use both techniques.

It is possible to use both techniques.

**PLEASE NOTE**: If you are using a Mikrotik router, you can find more information here:
