Jon's contributions went well beyond IANA -- he played a unique and pivotal role in the development and maintenance of the Internet in its first years.
His contributions started early -- he worked for Douglas Engelbart at SRI International where he helped develop the NLS system which became the second computer on the ARPANET, and he worked at the Network Measurement Centre for Leonard Kleinrock where he helped connect the first computer to the ARPANET.
He was the custodian of the domain, a founding member of the IAB, and a member of the ISOC.
He received many awards for his contribution to the Internet, including the Association for Computing Machinery's SIGCOMM award in 1987, and the International Telecommunication Union's silver medal in 1998 for his role leading the IANA. Due to the Internet growth during the 1990's there was also the need for an organization that would take responsibility over the central registration of domain names and addresses.This is how ICANN (Internet Corporation for Assigned Names and Numbers) was created.The second connects to the list of IANA Protocol Assignments maintained by the IETF Secretariat.Be advised that there is a brief time period when the two directories will be out of sync.IANA is responsible for coordinating some of the key elements that keep the Internet running smoothly.While the Internet is renowned for being a worldwide network free from central coordination, there is a technical need for some key parts of the Internet to be globally coordinated, and this coordination role is undertaken by IANA.IANA's birth can be traced to 1969, when Postel first started keeping lists of network protocol numbers on a scrap of notebook paper.Postel joined the Information Sciences Institute at the University of Southern California in 1977, and later became Director of the Computer Networks Division. Reynolds since 1983, he expanded the IANA staff and functions to keep the Internet running smoothly through the explosive growth years of the 1990's.Specifically, IANA allocates and maintains unique codes and numbering systems that are used in the technical standards (“protocols”) that drive the Internet.IANA activities can be broadly grouped in to three categories: The first choice below connects directly to IANA's web page.
