A “/24” network means 254 usable IP addresses, a /16 means 65,534! So, to make sense of this, let’s use some examples: an IP address with a Subnet Prefix such as “192.168.1.0/24” indicates that you are using the IP addressing scheme of 192.168.1.x with the subnet mask of 255.255.255.0 and you have the 254 usable addresses (1-255).

Aug 16, 2003 · [Understanding a subnet mask] Now that you understand what binary is, let's have a look at our two subnet masks from the beginning of my post: 192.168.1.0 / 255.255.255.0 192.168.1.0/24 The concept of a subnet mask is simple. You have a network and you have hosts on the network (anything with an IP address is a host).

Valid subnet address: To figure out the valid subnet address, simply subtract the subnet mask from 256. For example, if you had a Class A mask of 255.240.0.0, the equation would be 256-240=16. Solucionado: Invalid IP for this subnet mask entered
