DNS Redirector will act as DNS server for network clients regardless of their operating system. DNS Redirector should always be the first DNS server that clients use and not installed behind other DNS servers.

Only when used as an initial redirector (typically in a wireless HotSpot environment to show a welcome or advertisement page) the machine running DNS Redirector and all network clients must be in the same IP address space and cannot be separated by a router or firewall.

This is necessary to ensure DNS Redirector can track clients joining and leaving the network.
