If you are like me and feel like you maybe have memorized everything that can throw at you...

This is probably well known but I just now found it... great site for practice as it throws you many many more Class A's than does. I haven't clicked on the advanced subnetting button yet... but its nice to see things other than subnetting the private addresses

    is that even valid?

    Perhaps this isnt used, but I'd say it's possible. Address class A is 0 - 127 so yeah possible, but certainly a weird IP address.

    Network address :
    Broadcast :

    I'll probably leave it the experts to say whether this can be used in production as the network address is
