Increase DHCP Scope

Need to increase our DHCP scope as running out of usable addresses.

We currently use 172.16.32.x with a subnet of 255.255.0.0

Was looking at expanding the range on our Server 2008 r2 box to 172.16.32.x to 172.16.33.x utilising the same subnet.

Does this look ok, or would I need to make some more severe changes?

If your mask is already 255.255.0.0 then that is already in the same subnet so it should work. To test give yourself a static ip in the range and try it out.

If your subnet is 255.255.0.0, your scope is 172.16.x.x.  So assuming everything else is configured correctly, you should be fine using .33.x.

Private IP Address Ranges,

For Class B network 172.16.0.0 - 172.31.255.255 (/16 or 225.255.0.0)

For local network above IP range should be used.

Hi, you may want to consider reducing the network segment to /24 ( 254 hosts with 255.255.255.0 subnet mask). This will decrease collision domain and broadcast domain that can cause traffics.
