The smallest subnet you can create has a subnet mask of 255.255.255.252. This subnet has only 4 addresses, one network address, one broadcast address and two valid host IP addresses. This subnet is ideal for point-to-point links where we only require two usable IP addresses.

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. Are you trying to set up more than one machine? Or are you trying to give a single machine more than one address? – David Schwartz Jan 30 '17 at 23:44. add a comment | 3 Answers Active Oldest Votes. 4 /30 network gives you only two useable IP addresses What does /29 mean in IP subnetting?

By giving a second netmask, you can design subnets and supernets.

How To Subnet Subnet Mask Short-Hand. Now that we have basic subnetting figured out and know how to convert to binary, this will be a very brief section on subnet mask shorthand. Instead of writing out a full subnet mask such as 255.255.255.0, we can shorten this to /24. CIDR Conversion Table
