Select one of the following options to specify how Simple DNS Plus should respond to lame DNS requests:

 

Any data already cached will be provided.

 

Using this option, you specifically inform the client that you will not perform any recursion for them or provide any data for the requested domain name.

 

Using this option, simple port scanning will not reveal that you are running a DNS server.

This may make you a less interesting target for hackers.

 

Using this option, you can redirect the client to a sign up page, or to a page informing the client that he is using a wrong DNS server.

 

 

Background:

 

A "Lame DNS Requests" is a DNS request sent to a DNS server which is not configured with the requested domain name (local zones or otherwise) and not configured to perform recursion for the IP address sending the DNS request.
