David H. Crocker is a Senior Advisor of the Messaging Anti-Abuse Working Group, active in the IETF, and self-employed working under the company name Brandenburg InternetWorking. He designs network-based applications businesses and system architectures. He has forty years of work experience in the Internet industry, including early work with DARPA and designing the basis for today's email system.
He is currently a member of the IETF's administrative and legal oversight bodies (IAOC/Trust). He is also a member of Association of Computing Machinery, Institute of Electrical & Electronic Engineers, and ISOC.
Mr. Crocker is well-known for his work on RFC 822, which was the first standard to describe the syntax of a domain name. He is the brother of Steve Crocker, who is also well known in the Internet Industry for his pioneering work, such as creating the RFC series.
Much of Crocker's recent work revolves around email anti-abuse, working towards a trust overlay on the Internet.
From 1989 to 1991, he worked as the Manager of Network Systems Laboratory, Digital Equipment Corp. Prior to which he was the Vice President of Engineering at The Wollongong Group, Inc. He has also held the position of Development Manager at Ungermann-Bass, Inc. and has worked as the Director of System Development at MCI Digital Information Services Corp, where he worked with Vint Cerf to build the company a national email service. Prior to this, he worked as the Co-Principal Investigator, Electrical Engineering at University of Delaware.
Work with the Internet
He has been the Area Director for the IETF from 1989-1996. He participated in the effort to standardize facsimile, and electronic data exchange over the Internet. He chaired the Silicon Valley–Public Access Link in the early 1990s.
For almost 40 years he has been designing and preparing Internet standards. He has also contributed to work on Internet commerce, domain name service, emergency services, and TCP/IP enhancements. He was one of Jon Postel's appointees to the IAHC. He has also taught several classes on Internet, TCP/IP and Open Systems Networking.
Mr. Crocker is responsible in part for the facilitation and growth of email. He developed MS, based on the design of MSG, which was the first modern email sender program. MS was designed for UNIX operating system. The idea was initiated by Steve Walker, who was then the Program Manager at DAPRA. Mr. Crocker designed the functional specifications and Steve Tepper and Bill Crosby did the programming, reporting to the Rand department head, Bob Anderson.
In 1977, Mr. Crocker, John Vittal, Kenneth Pogran, and Austin Henderson worked together on a DARPA initiative that was meant to collect various email data formats into a single, coherent specification. The result of their work was RFC 733. In 1982, Dave revised RFC 733 and prepared RFC 822, which was the first standard to describe the syntax of domain names.
In 1978, Mr. Crocker was once again with Dave Farber at the University of Delaware, where they developed the first versions of what would become the Multi-purpose Memo Distribution Facility (MMDF). This project was for the U.S. Army Materiel Command, and served as the foundation of CSNet. He has developed two national email services and designed two others.
Mr. Crocker actively participates in meetings in the Internet industry. He has chaired and presented at several conferences, including:
- N+I Interop
- Electronic Messaging Association
- APRICOT '06, '05, '04, '99
- RIPE, Edinburgh
- EMail World
- Unix Expo
- FTC email authentication conference in 2004.
He is the author of book chapters, magazine articles, presentations and specifications on open systems networking, standards, electronic mail and electronic commerce. A complete list of his presentations and publications can be read here.
