Passive DNS or pDNS is a service which records domain name system server (DNS) answers to DNS client requests.
In order to see the evolution of records over time, a history is recorded.
Various sources can be used to build a large sensor network.

Enabling the D4 passive DNS sensor in AIL will contribute resolved domains and host to the global Passive DNS community operated by CIRCL.lu
