Question : How can I reserve address ranges?

Hi there,

we want to set up DHCP (on Win 2003 Server) in our growing network and have the plan to use the subnet from 192.168.0.0 to 192.168.7.254, Subnetmask 255.255.248.0 for all clients.

We also would like to give DHCP some "rules" to reserve address ranges for different kinds of network devices, e.g.

* Clients should get 192.168.3.x
* Win-Servers should get 192.168.6.x
* Linunx-Servers should get 192.168.7.x
* Printers should get 192.168.4.x

Is this possible at all without reserving every single address? And if yes, how?

In the documentations we read, we only can find rules to divide the given DHCP options like time servers etc. depending on the clients properties. But I can see no way to divide the given IP-address itself.

Many thanks in advance!

Answer : How can I reserve address ranges?

In your particular case, I think you should just make your DHCP offer IPs in your 192.168.3.* range - which is the only "variable" stuff in your company. You're not changing your servers, printers every day, are you?
Every server and printer should be configured with fixed IP addresses - if you want the DHCP server doing the job - you'll have to link their MAC addresses to specific IP addresses in your DHCP, in some small ranges that are not available dynamically ; but that might look oversized, too :)

Then create some manual entries in your DNS server, with organized names, (lnxsrv01, winsrv01, pr-xerox..., whatever).
This way everyone can see everything in the network neighborhood and understand what this equipment is.

how does it sound ?
