Since twenty people asked off-list, I'll just tell you that the
software we're currently using for logging/tracking of MAC/IPs is
Cacti (cacti.org I believe) and the add-on called "MacTrack".

The desktop group here actually uses their AV software to detect rogue
computers - scanning machines to verify the AV software is installed
and has the latest definitions (obviously, if it doesn't, it's not one
of theirs). This isn't free.

I would make jokes about your last comment, but I'm too weirded out by
this whole thread to even try. The company I work for, which is hardly
at the forefront of security, can tell you when a new machine is added
to the network, the instant it is added. Very soon, we'll be
implementing port security on all of our switches and a centralized
log server to gather data from every device on our network.

Your reasons for wanting to dump DHCP are as flawed as the original
poster's reasoning. Right now I can log into a FREE piece of software
I have implemented here and tell you what MAC address had which IP
address - for any period of time going back 2 weeks (and I could
configure it to keep the records longer). Eventually everything will
be getting logged in such a way that I'll be able to tell you when an
"incident" occured, on what network, via which MAC address on which
port of which switch...etc. I will be doing all of this with freely
available, open source code that you could download and install right
now...if you were in a position to do so.
