One more information for you, IP address start with 192, it's not class B. It's class C.

The size of a network is no longer determined by the first octet.

The private use space at 192.168 is large enough to host a class B (/16) network if desired. Of course, the OP is clearly requesting a series of class C (/24) networks based on his requirements. Odd, since he obviously sees it at one large network.
