A system, apparatus and method to use private IP addresses to designate host devices or nodes in different networks for communication purposes are described. Various embodiments of the invention address the problem of a shortage of public IP addresses under IPv4 architecture. In one embodiment of the invention, dynamic NAT penetration capabilities are provided which consequently expand the capability of running peer-to-peer applications on the Internet.

Communication using private IP addresses of local networks

Storage using resemblance of data segments is disclosed. It is determined that a new segment resembles a prior stored segment. The prior stored segment comprises a segment stored previously from any location in an input data stream. A delta between the new segment and the prior stored segment is determined. A representation of the new segment based at least in part on the delta is stored.
