can dhcp work in two different virtual s

By pcarbonaro ·
we outgrew our first subnet range of 192.168.1.0 and we were given another subnet range of 192.168.4.0 these both are on the inside of a router that uses nat so our dhcp will not have to cross a router. we installed a dhcp server on a server that resides in the first range of 192.168.1.0 but because we were out of addresses in that range we created a scope of addresses that was in the range of 192.168.4.0. when we tried to log on and get an address from the dhcp machine we did not it. I am wondering if dhcp will work when configured like this.

can dhcp work in two different virtual s

It all depends upon your subnet mask. In order for both of these address ranges to be on the same subnet, your subnet mask has to be configured properly in the DHCP scope. If this is a totally private network (not connected to other 192.168.x.x networks within your company), then you can simply use a subnet mask of 255.255.0.0 for both scopes. Otherwise, check with whoever is assigning these addresses for the proper subnet mask. If in fact your subnet mask is such that these are not on the same subnet (i.e., your default subnet mask is 255.255.255.0, 255.255.254.0 or 255.255.248.0) you have to do some routing on your NT server in order for this to work. That is too complicated to explain here but if you need some help feel free to email me at synergy@synoffsys.com. Good luck!

You can either add routes to your NT server or I would rather add another IP address to the NT machine with the same subnet mask as the first one. then re-configure the DHCP to add the new address range

The first two answers cover this material fairly well. Since you have a routers working with between the two subnets I think all you need to do is install the "DHCP Relay agent" on a machine in the new subnet.

If you are using a subnetmask of 255.255.255.0 with the above address ranges, you can install two scopes - one in each range. But then you have to "route" - even so it looks flat. Your router will have to have DHCP/BOOTP forwarding enbled. Or youcan install separate NT servers in each subnet with separate scopes.

If you are using a subnetmask of 255.255.0.0 (or 255.255.248.0, the subnet mask that partitions 192.168.1 through 192.168.4 in the same subnet), you have to create on DHCP scope(192.168.1.1 through 192.168.4.254) and exclude the ranges in between that you do not want to be part of DHCP (i.e., 192.168.1.255 through 192.168.4.0). Remember to exclude your network address (typically x.x.x.0) and broadcast address (typically x.x.x.255).
