DNStester
Test Description
DNStester uses Windows DNS API functions to make a recursive DNS query to the Internet server. DNS packets can
be used to transfer extra data and this is why they should be controlled by firewalls as any other packets.

After initialization, DNSTester asks your permission to attempt a recursive DNS query. To pass the test, your firewall ought to block this request and produce an alert.
