By configuring Access settings, you can protect your AdGuard DNS from unauthorized access. For example, you are using a dedicated IPv4 address, and attackers using sniffers have recognized it and are bombarding it with requests. No problem, just add the pesky domain or IP address to the list and it won't bother you anymore!
Blocked requests will not be displayed in the Query Log and are not counted in the total limit.
How to set it up
Allowed clients
This setting allows you to specify which clients can use your DNS server. It has the highest priority. For example, if the same IP address is on both the denied and allowed list, it will still be allowed.
Disallowed clients
Here you can list the clients that are not allowed to use your DNS server. You can block access to all clients and use only selected ones. To do this, add two addresses to the disallowed clients: 0.0.0.0.0/0 and ::/0. Then, in the Allowed clients field, specify the addresses that can access your server.
Before applying the access settings, make sure you're not blocking your own IP address. If you do, you won't be able to access the network. If that happens, just disconnect from the DNS server, go to the access settings, and adjust the configurations accordingly.
Disallowed domains
Here you can specify the domains (as well as wildcard and DNS filtering rules) that will be denied access to your DNS server.
To display IP addresses associated with DNS requests in the Query log, select the Log IP addresses checkbox. To do this, open Server settings → Advanced settings.
