The /16 subnet mask is a subnet mask commonly used for class A networks. It consists of IP addresses ranging from 10.0.0.0 to 10.255.255.255. /16 subnet mask is the default subnet mask for Class B networks. The dotted decimal notation for a /16 subnet mask is 255.255.0.0, which is derived from the binary representation 11111111.11111111.00000000.00000000.

/22 A subnet mask is a subnet mask with a dotted decimal notation of 255.255.252.0 and a wildcard mask of 0.0.3.255. /22 subnet masks divide larger networks, like class A and class B networks, into smaller networks (subnetworks). Each of the subnetworks has a range of 1024 IP addresses. The first IP address in this
/23 subnet mask is a subnet mask with 255.255.254.0 as the dotted decimal notation and 0.0.1.255 as the wildcard mask. /23 subnet mask divide larger network like class B network and Class A networks into a smaller networks(subnetworks). Each of the subnetworks has 512 range of IP addresses. The first IP address in this range
The /24 subnet mask is the default subnet mask for a class C network, which includes all networks from 192.0.0.0 to 223.255.255.0. /24 subnet mask has a dotted decimal of 255.255.255.0, and this is obtained by converting its binary representation, 11111111.11111111.11111111.00000000, into a dotted decimal. A /24 subnet mask gives 256 ranges of IP addresses.

The /25 subnet mask divides a large network into multiple smaller subnetworks. Each of the subnetworks comprises 128 ranges of IP addresses. The first IP address in this range is reserved as the network address, while the last IP address in this range is reserved as the broadcast IP address. Hence, there are 126 usable
