The practice of encapsulating IP packets within DDP was originally developed at Stanford University34 as the Stanford Ethernet - AppleTalk Gateway (SEAGATE) by Bill Croft in 1984 and 1985.5
The SEAGATE hardware was commercialized by Kinetics in 1985. The Kinetics Internet Protocol (KIP) was used to integrate with their FastPath LocalTalk-to-Ethernet bridge.6 Apple Computer embraced the use of the encapsulation technology, which came to be known as MacIP.
One of the mandates for the Internet Engineering Task Force (IETF) "IP over AppleTalk" working group was to document existing MacIP implementations and to develop a specification for MacIP that could be proposed as a standard.7 A draft document was submitted, however it was not accepted as a standard and has subsequently expired.8910
