RE: Down with DHCP!!!!

Totally agree, I could not imagine running any network with more than 10
machines without DHCP.  It's one of the protocols that actually make life
easier for sys admins, and when setup correctly you can know exactly who had
the lease at any given time.

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.

I, too, would like to do away with DHCP. Not only for the reasons you have
outlined, but also because it is easier to track incidents back to a
specific host, without worrying about whether or not the lease has expired.

Unfortunately, I am not in a position to mandate that change.
