Automatic server discovery

Automatic server discovery is a software licensing feature that allows client applications to find license servers automatically on the network, thus eliminating the need for end users to manually configure server information and allowing system administrators to perform their tasks more easily and efficiently. If you have, for example, over 70 machines then the configuration process will take a long time if it is done manually.

Automatic server discovery often uses Multicast UDP to send broadcasts, to which available license servers respond with information about their network location. When a licensed server is discovered, the information is locally cached on the client machine, so automatic server discovery does not have to be performed at each application startup.

The newest version of NTP also supports Automatic server discovery. There are three schemes provided by NTPv4:
 * Broadcast / Multicast
 * Manycast
 * Server pool

Automatic server discovery typically works only on local networks, and will not work on WAN or VPN connections.
