'''David H. Crocker''' is a Senior Advisor of the  [[MAAWG|Messaging Anti-Abuse Working Group]], active in the [[IETF]], and a self-employed consultant, working under the company name Brandenburg InternetWorking. He designs network-based applications businesses and system architectures.<ref>[http://www.dcrocker.net/resume.html dcrocker.net]</ref> He has forty-five years of work experience in the Internet industry, including early work on the [[ARPANET]], including designing and standardizing Internet mail services.
'''David H. Crocker''' is a principal with Brandenburg InternetWorking. He designs network-based applications businesses and system architectures. He worked in the ARPA network research community during the 1970s, and led product development efforts at MCI and various Silicon Valley companies, during the 1980s. He then founded several startup companies, serving as CEO for one. Dave developed and operated two national email services, designed two others, and was CEO of a community non-profit ISP. His senior management product efforts cover email clients and servers, core protocol stacks for TCP/IP and OSI, network management control stations, and knowledge management tools for product support. Dave has a B.A. in psychology from UCLA, M.A. from the Annenberg School of Communications at USC, and he studied computer science at the University of Delaware.  


Dave has authored and contributed to Internet standards for thirty-five years, covering Internet mail, instant messaging, facsimile and EDI. He has also contributed to work on Internet security, ecommerce, domain name service, emergency services, and even some TCP and IP enhancements. He has authored more than 45 IETF RFCs. Dave served as an Area Director for the Internet Engineering Task Force, variously overseeing network management, middleware and the IETF standards process. For his work on email, Dave is a co-recipient of the 2004 IEEE Internet Award.  
He has held a variety of positions in the IETF, as one of its first area directors, chairing working groups, and serving on the administrative oversight committee (IAOC/Trust).<ref>[http://bbiw.net/dave.html bbiw.net]</ref> He originated training for IETF working group chairs and co-authored an RFC describing working group processes. He is also a member of [[Association of Computing Machinery]], [[Institute of Electrical & Electronic Engineers]], and [[ISOC]].<ref>[http://bbiw.net/resume.pdf bbiw.net]</ref>


Dave is active with anti-abuse efforts for DKIM, and BATV, as underpinnings for evolution to a trusted email infrastructure. While at Digital Equipment Corporation, Dave initiated an internally funded project for open enhancement of the then-problematic BIND software used by DNS servers. Dave has been active in DNS policy work. Jon Postel named him as a member of the IAHC and he was editor of its proposal to add more top-level domains to the DNS. Its recommendations formed the basis of the eventual enhancements to domain name administration. Dave also was active in the ICANN Non-Commercial Domain Name Holders Constituency.  
Dave is well-known for his work on RFC 822, which defines the format of an Internet mail message and was the first 'customer' specification using [[Domain Name|domain name]]<nowiki/>s. 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 and chairing the ICANN board.


Dave and Steve Crocker are brothers. Steve Crocker went to the same high-school as Jon Postel and Vinton Cerf. At MCI, Dave worked for Vint.
Much of Crocker's recent work revolves around email anti-abuse, working towards a trust overlay on the Internet.<ref>[http://tools.ietf.org/html/rfc5672 ietf.org]</ref>
