Perhaps the architects of the Internet suspected a revolution was coming and the infrastructure that had served the networks of research labs and universities well for some 15 years wasn't going to be up to the task. Surprisingly IPv4, the fifth version of the defining protocol upon which the modern Internet is based, has held up an additional 10-plus years, but, change is in the air. Those interested in the predecessors of IPv4 can find a list of references for where to read about IPv0 (yes, there was a version 0) through IPv3 in RFC 762. The ...
