<DIV><SPAN class=571184923-09062008><FONT face=Arial color=#0000ff size=2>as far
as I know, there are NO implementations of DHCP Authentication, despite it being
defined with a relatively mature RFC (in the sense that after an initial flurry
of discussion, there were no updates offered, suggesting that (1) the RFC
was solid as written, or (2) no one cared about implementations. As
with any authentication system, the principle problem is key distribution, and
no scalable method was ever offered to support client
Authentication.</FONT></SPAN></DIV>

<DIV><SPAN class=571184923-09062008><FONT face=Arial color=#0000ff size=2>Many
organizations authenticate *USERS* through RADIUS, which is significantly
easier to scale, while some substitute Wireless Access Point and
Router client MAC address filters for *CLIENT* </FONT></SPAN><SPAN

size=2>authentication. The former is an established, mature protocol for
user authentication and has many implementations and management tools.
Managing client MAC address filters for Wireless Access Points and Routers has
an even worse scalability problem than simple key distribution to a client,
although I have heard admins boast (or complain?) that they were using it in
their networks.</FONT></SPAN></DIV>

<DIV>I am a student and would like to know if it is possible to make a dhcp
