Hi, This is my first post. I am studying for the 291 test. In dhcp i came across the term "multinetting". I understand the basics, that it allows for multiple subnets on the same physical subnet. But I have never really read anything in depth on the subject, and would consider myself fairly well versed in tcp/ip. Could anyone point me to further study, how it is implemented, etc? I hate only knowing something vaguely, it drives me nutz. tia norm btw if subnetting is used to limit a broadcast domain, why multinet? i take it the custom subnetting and multinetting are mutually exclusive?
