The first working version that was widely deployed was assigned version number 4. [10] A separate protocol based on reliable connections was developed and assigned version 5.

Private IP addresses as described in RFC 1918 are usable only on private networks not directly connected to the internet.
AT&T Computer Systems (abbreviated AT&T-CS) was the home of the UNIX System V operating system, originally developed in the Bell Labs Research Division. The important System V Interface Definition (SVID) was written, attempting to standardize the various flavors of Unix , and define the official interfaces which made up a Unix operating system.
The gateway operates at the network layer (Layer 3) of the OSI Model. The gateway is used when transmitting packets. When packets are sent over a network, the destination IP address is examined. If the destination IP is outside of the network, then the packet goes to the gateway for transmission outside of the network.
As shown in the diagram below, a T.38 gateway is composed of two primary elements: the fax modems and the T.38 subsystem. The fax modems modulate and demodulate the PCM samples of the analog data, turning the sampled-data representation of the fax terminal's analog signal to its binary translation, and vice versa.
