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:

192.168.0.0 Refers to the IP adress /24 refers to the subnet. /24 subnet is 255.255.255.0. 192.168.0.0/24 is common for home networks. http://www.skullbox.net/subnetcalculator.php
