That is a code that basically specifies the size of a network or subnet. It is basically equivalent to the subnet mask, but written differently.
It does not require a subnet mask.
If this is a default subnet mask, then it would be a class C subnet mask. If you are subnetting a network and this is not the default subnet mask, then it could be either a class A or class B.
The default subnet mask would be 255.255.0.0
The default subnet mask has a standard size. The custom subnet mask allows you to make subnets that are smaller or larger than the default.
The default subnet mask is 255.255.0.0
Default Subnet mask: 255.255.0.0
default subnet mask for 198.25.4.129
It is called a subnet mask. A subnet mask is used for dividing IP addresses into host and network addresses.
