Creating a 9bit Class C subnet
I am thinking about changing my companies subnet from 255.255.255.0 to 255.255.254.0 open up more available DHCP IP Addreses. the current subnet is 192.168.10.1 through 192.168.10.100 reserved for Static and 192.168.10.101 through 192.168.10.254 both with 255.255.255.0 for the subnet. My question is, can I simply go into the Server 2008 DHCP server scope options and change the DHCP subnet setting to .254 specifically only for the DHCP clients? Or will I have to do both that AND chance all of my server,SAN,networking devices, etc network adapter settings to 255.255.254.0 as well in order for the DHCP clients and servers to still be able to communicate?
thanks
thanks

Ok, one thing I'm still not sure I understand is what to do about the third octate, 255.255.?.X. For each static IP I currently have on each machine that is 192.168.10.x, what do I need to make the third octate? Or will i even need to change that? Just leave the Statics IPs all 192.168.10.x? And just change the DHCP scope to start at 192.168.10.100 and end at 192.168.11?.254? or does it matter what I make the third octate in the end of the scope, meaning could I theroetically make whatever I want?
thanks

to assist in changing the DHCP assigned submet masks, change the lease time to an hour and leave for a week or so. That way all dhcp clients will update within half an hour of you changing the subnets and save you running around
