Re-building DCHP

[Chris]

I need to re-build my company's DHCP scope because it
doesnt suit our needs anymore. My concern is, what
happens to all the static IP's that are placed on the
server and printer? Is there another way of adding more
DHCP scopes with one nic on the firewall and one nic in on
the server.

What happens to static IPs? Nothing, unless you change them yourself.

What are you changing from/to in this rebuild?

Re adding another NIC - no, that isn't going to help you. What are you
trying to end up with? If you tell us that, perhaps someone can advise...

We are needing more IP's. We are close to running out.

I am trying to have to subnets see each other. I have a
192.168.0.0 /24 & 192.169.0.0 /23. I need these 2 to
talk to each other and get to the internet.

You can't use 192.169.0.0/23, because that is not an RFC1918 range.

If you need more addresses (you are currently yousing 192.168.0.0/24, which
means you have 255 IPs between 0.0 and 0.255), I'd recommend increasing your
scope to 192.168.0.0/16 which would give you 65K IPs between 0.0 and
255.255. Adjust the scope, routers, and other static IPs to recognize a
subnet mask of 255.255.0.0, and you're set. This is an overkill solution, I
admit (because a CIDR of somewhere between 21-23 would give you more than
enough IP's), but it will entail the least changes to your network as well
as being easy to calculate.

Why do workstations have static IPs in a DHCP capable environment? The
printers, I understand...

Will I need to go to each PC and configure the statics. I have about 100

printers & PC's using static IP's
