Expand Network 10.10.x.x.

Have a corp network we are looking to expand - here are the details; bit of an amateur with notation so please be kind.

gateway and firewall: --

clients: thru  subnet mask:

DHCP provided to clients from W2003 Server - thru 200 -- (WE ARE MAXED OUT)

most of our servers are in the thru 30 range... workstations are scattered throuhout the network using static IPs.
