What is the meaning of "192.168.0.0/24" RRS feed

  • Question

  • Hi,

    I wonder what is the meaning of "192.168.0.0/24"?

    I am familiar with IP address rules but not familiar with "/24" format. What is the format name?

    A link to an online article that explain the format would help.

    Thank you,

  • this is CIDR format.  There are two parts to an IP address, the network number and the host number.

    The subnet mask shows what part is which.  /24 means that the first 24 bits of the IP address are part of the Network number (192.168.0) the last part is part of the host address (1-254).

  • hello Allan49, the /24 is referring to the subnet mask.  /24 indicates that the first 24 bits of the address are masked (255.255.255.0).  a /16 would translate into 255.255.0.0.  Here is some more information you can refer to:
