DNS Sensor Example

This shows two different types of DNS Requests. The first one does a "DNS Lookup" by making a type A query:

The configuration of the sensor looks as follows:

DNS Settings        

Server IPs

The IP adresses of one or more DNS servers.

Query Type

The type of the query. In this case type 'A' queries a IPv4 address.

Query Text

The address which should be checked. In this case 'www.example.com'.

In contrast, the configuration below shows a reverse DNS lookup via the PTR query:

DNS Settings        

Server IPs

The IP adresses of one or more DNS servers.

Query Type

The type of the query. In this case type 'PTR' queries a domain name pointer.

Query Text

The address which should be checked. In this case 'www.example.com'.
