I am currently working with a company that is using ip's of 206.92.35.1 -.254.

In about a month we will be changing the ip scheme to 192.168.1.*. How many ip's will i be able to use by using 192.168.1.*? I am currently using about 200 ip's for pc's and other network equipement and I want to make sure that I have enough available ip's for future growth.
