    Does a segment contains MAC address?

    Segment do not contain MAC address, it is Frame at layer-2 which contains source and destination mac address.

    In the CCNA chapter 4 quiz question #2 declares 172.15.1.0/16 a private address - why is this? Doesn't the closest block of private IPs start at 172.16.0.0? If the 16 bit subnet mask somehow brings this into range I'd love a better explanation.

    Similarly a later question implies that 192.169.2.2 is a private IP address too, is this a mistake?
