The Registry menu enables you to set up the registry server for your device. If you are using
a dynamic IP address for the VP-504(H)/508(H), you can set up the device to post its IP
address to the VPON registry server. You can then look up your IP from the MAC address
or server name. You can use the registry server to give a name to the VP-504(H)/508(H)
also.
