Network Migration
=================
Currently I have a rather large (40+) network setup of (private) static IP
machines (Win32's, Mac's, Unix's, and some network HP and IBM printers). Looking at
what I've been working on, and building on over the past 7 years basically resulted in
one big, very inefficient mess. I'd like to migrate this whole slew to a DHCP
environment to make my life easier - if at all possible. However, a few things come
to mind here:
Some of those printers need to have a static IP since the print server software
relies on that IP. I need to be able to apply different rules to some of the
computers, in terms of who is allowed to browse the net, at what times of the day,
who's not allowed to access the net at all, etc., etc. (and to be able to do some
accounting on the bandwidth used on each client.) This has worked well on the now
pre-historic machine which is failing about once a week now (so I need to move fast
with this). Moving to a DHCP environment, means I start from scratch since A) I've
never managed a DHCP network before and B) I wouldn't know where to start with the
rules as explained above.
So I wonder. Can I have both a static and a DHCP environment intertwined
together? Can I replace the current, aging server, with another one, setup the same
way (with static routing and all), then put a DHCP server on the same network and
slowly start moving client machines over to DHCP once I figure out what needs to
happen?
What happens with those devices that absolutely need to have a static IP? How
would that work in a DHCP environment? How would I apply rules to each individual
machine if their IP changes occasionally? In terms of our internal mail relay, which
relies on IP addresses resolving to the individual machine (for accounting purposes),
if the IP changes, the hostname no longer matches, consequently the mail server might
reject the relay all together.
I'd really appreciate some comments on this. Should I go to a DHCP setting (and
hope my life will be easier), or do I continue battling what we have now? Eventually
the pre-historic server will have to be taken down, if it doesn't take itself down one
of these days, so I need a solution fast.
