255.255.255.0
The correct term is subnet mask instead of subnet mass. A subnet mask separates an IP address into the host address and the network address. It is a 32-bit number that can mask an IP address.
Example IP address of 192.168.1.123 with a subnet mask of 255.255.255.0
This is a network address
255.255.255.0
what is the subnet mask for this hst IP prefix format ? Host IP Address: 183.91.104.16
Because each IP defines certain subnet mask.
Subnet mask for the above is 255.0.0.0
if the ip address is 192.168.2.1 then the subnet mask should be 255.255.255.0
it is a class c address..so default subnet mask is 255.255.255.0 it is a private address...
255.255.0.0
That depends on the subnet's subnet mask.
There is no set subnet mask for different ip configurations. The most common default subnet mask is 255:255:255:0 though, if that helps.
