Subnetting

[Bryan]

My company was originally setup with a DHCP scope of 254
addresses /24 bit subnet. Recently we have begun to out
grow that. I have 20 switches and 7 servers and the last
thing I want to do is change each an everyone of there
subnet masks to a /23 bit subnet. Is there an easier way
to do this.

That's the beauty of DHCP. change the scope on the DHCP server. Have all
of your clients shut off their machines when they go home. Activate the new
scope, and when the clients boot up in the morning, they will have the mask
change.

Be aware though, that you will manually have to change any static IPs on
devices such as servers and routers. Also an alternative to having the
clients shut down, is to have them do an IPConfig /Release and IPConfig
/Renew
