DHCP: Running out of IP addresses in the scope

I have a windows 2000 domain with a DHCP server.
My current network is 10.151.x.x/ with all servers on the 10.151.10.x/ subnet & the DHCP clients in the subnet 10.151.50.x/ My current DHCP server is configured with scope 10.151.50.x/ Now I'm running out of IP addresses in the current subnet. I need another subnet 10.151.51.x/ to be added. Is this possible? Can I add another DHCP server in the same network to serve this new scope? Or should I change to VLAN switches?

Technically speaking, 10.151.50.x with a mask of is in the same network as 10.151.51.x with a mask of  Indeed, all of 10.151.x.x with a mask of is in the same network, that's what the mask tells us.  If you are running low on dhcp space in the range of 10.151.x.x, and there is rooms above, in the for example, simply extend the dhcp range that you have.

If you prefer, you could add another range, but I believe that it would un-necessarly complicate things.

If you wanted to add another DHCP server to manage the additional space, that's fine.  It's not required, but it would be recommended.  This would allow a backup if your primary DHCP server developed a problem.  If you do this, however, you want to make sure that your addresses ranges don't overlap between the two servers.

Hope this helps,

Thanks Alan for your answer. I was not sure whether I can extend my DHCP scope as such. Now I've extended the scope as & excluded the IP addresses & Now things are fine.
