    10.0.0.0/8
    contains
    10.0.0.0/9
    10.128.0.0/9
    which contains
    10.0.0.0/10
    10.64.0.0/10
    10.128.0.0/10
    10.192.0.0/10
    which contains etc etc, like a tree

    So any ip with 10.x.x.x and a mask 9 bits or longer can be summarized by 10.0.0.0/8
    Networking, sometimes i love it, mostly i hate it.Its all about the $$$$
