    I hope I understood your question correctly.

    /27

    255.255.255.224

    Here are the valid IPs. I am assuming subnet zero is used. I am not including the broadcast IP address

    216.21.5.1 - 216.21.5.30
    216.21.5.33 - 216.21.5.62
    216.21.5.65 - 216.21.5.94
    216.21.6.97 - 216.21.5.126
    216.21.6.129 - 216.21.6.190

    150.5.0.0
    32-9=23
    255.255.254.0

    150.5.0.1 - 150.5.1.254
    150.5.2.1 - 150.5.3.254
    150.5.4.1 - 150.5.5.254
    150.5.6.1 - 150.5.7.254
    150.5.7.1 - 150.5.8.254
    I'm an Xpert at nothing apart from remembering useless information that nobody else cares about.
