Chat Service Reverse DNS Lookup

This enumeration is used to indicate the level of Reverse DNS Lookup authentication, and is used by ChatService.ReverseDNSLookup. Reverse DNS Lookup attempts to resolve a chat client's IP address before allowing the client to connect to the service.

The level of Reverse DNS authentication can be one of the following:

Chat_Service_ReverseDNSLookup enumeration Meaning
ctReverseDNSDisable Reverse DNS Lookup not used.
ctReverseDNSAttempt Authentication is attempted, but does not prevent chat user from connecting to the server if lookup fails.
