  • IP Addressing and Subnetting Question?

    Novice to Networking,

    I'm reading information on IP addrress and subnetting, and I've notice the following on the forum:

    172.16.0.2/24
    192.168.65/27

    I understand which portion of the IP Address is the Network Id and Host ID, but I do not know what /24 and /27 is.

    Could someone assist me in determine the meaning?

    Thanks

    /24 =255.255.255.0
    /27 =255.255.255.224

    /24 or /x(x) means how many bits you're using for the subnet

      For more details, check out this wiki on CIDR, which is the representation of the subnet mask as a /27 or a /24.

        Dumber & Boondock,

        Thanks - For the explaination. The information was helpful Especially the IPV4 subnetting reference table.
