Subnetting a Class B network address - TechRepublic

Understanding subnet mask is a key element to define the length of IP subnets. It can assume the following values: 128, 192, 224, 240, 248, 252, 254, 255. Subnetting a Class B network address - TechRepublic May 29, 2001 CIDR Conversion Table A network is called a supernet when the prefix boundary contains fewer bits than the network's natural (i.e. classful) mask. A network is called a subnet when the prefix boundary contains more bits than the network's natural mask.. Examples 209.60.128.0 is a class C network address with a natural mask of /24. 209.60.128.0 /22 is a supernet which yields: Set up 4 ip addresses with Subnet mask 255.255.255.252 (30) Are you using the Subnet mask 255.255.255.252 with your IPs? – CIA Sep 16 '15 at 21:06.
