DaveLembke is right. More detail is needed.
Any IP that ends in .0 is a base address for a subset.
The address that ends in .255 is reserved.
Therefore up to 254 cn be assigned. Which means you might have five routers in one subset. Maybe.
Router at 192.168.1.1 could assign from .2 to..51
Router at 192.168.1.52 could assign .53 to 102.
Router at 192.168.1.103 could assign .103 to .153
