> "Dynamic Host Configuration Protocol for IPv4 (DHCPv4) Threat 
> Analysis" provides a comprehensive threat analysis of the 
> Dynamic Host Configuration Protocol.  DHCPv4 (RFC 2131) is a 
> stable, widely used protocol for configuration of host 
> systems in a TCP/IPv4 network. RFC 2131 did not provide for 
> authentication of clients and servers, nor did it provide for 
> data confidentiality. This is reflected in the original 
> "Security Considerations" section of RFC 2131, which 
> identifies a few threats and leaves development of any 
> defenses against those threats to future work. Beginning in 
> about 1995 DHCP security began to attract attention from the 
> Internet community, eventually resulting in the publication 
> of RFC 3118 in 2001. Although RFC 3118 was a mandatory 
> prerequisite for the DHCPv4 Reconfigure Extension, RFC 3203, 
> it has had no known usage by any commercial or private 
> implementation since its adoption. The DHC Working Group has 
> adopted a work item to review and modify or replace RFC 3118 
> to afford a workable, easily deployed security mechanism for 
> DHCPv4. This memo provides a comprehensive threat analysis of 
> the Dynamic Host Configuration Protocol for use both as RFC 
> 2131 advances from Draft Standard to Full Standard and to 
> support our chartered work improving the acceptance and 
> deployment of RFC 3118. This draft is available as
