Means for masquerading IP addresses for non-IP devices are disclosed, enabling non-IP devices or sub-networks having incompatible address spaces to be connected to an IP network and appear as addressable network objects. In one embodiment, the means may be a remote system controller (RSC) that has a block of IP addresses assigned to it for use with connected sub-networks or devices. Normally each assigned address will be associated with a management information base (MIB) containing data about the associated device, and each MIB will be associated with a protocol converter and I/O port connectable to the respective device or sub-network.
