how many routers(xbees2) can add under coordinator (Xbee S2B pro)

please help me,
that i’m trying to connect 100 routers under a coordinator but they are not in N/W consistently,
so any one can tell me how many routers can add under a coordinator.

‘N’ number of Routers can be joined to a single Coordinator.
The maximum size of ZigBee network can be 64k.

Thank u 16ksa23,
but i need N/W consistency,i mean in that N numbers some routers are deviating from N/W,So i cant get data from them,
please tell me that how can i set a n/w for N/W consistency…is there any other source.
