    Again the problem is not the 50 ip addresses, but how they are connected.
    If they are all in the same area you have the problem of collisions and the
    problem of increased traffic due to updating the routing tables for all 50
    nodes. Where as if you have smaller areas, one computer will be arbitrated
    as the router in each area and the collisions will be less because of the
    smaller areas. Having many computers in the same LAN is always a problem
    with Ethernet. If you have many computers in the same area then token ring
    is better because of the reduction of the collisions, but token ring does
    not solve the routing table problem.
