These numbers are useful for IP networking and help determine where a subnet can be properly broken up into smaller subnets.

When calculating subnets and subnet masks, there are special numbers that reoccur and remembering these numbers is essential. Continuing from the example, the subnet for IP address length of the subnet mask 255.255.255.252 is 2. The number of 0s a binary mask has is directly related to the subnet length. You could use our calculator or do it the long way: An example of subnet IP address is as follow: a 255.255.255.252 subnet mask has a binary mask that is 11111111.11111111.11111111.11111100. It can also determine the size of a subnet and, if the IP address on a subnet is known, the subnet mask is used to determine where the endpoints of the subnet are.

What Is a Subnet Mask Address and What's It Good For? A subnet mask boils down to 'masking' out the host bits of your IP leaving only the Network ID visible. One of the most useful functions of our IP calulator is the ability to show you subnet information. If you're buying a usable block of IPs for your business, it would be tedious to calculate all the things necessary for your networking purposes by hand or ledger. If you don't know, there are a total of 4,294,967,296 possible IP addresses in IPv4. The calculator is useful because it does the work for you. Fortunately for you, Colocation America has your back with our IP range calculator suitable for all ages! Just plug in your IP range to figure out your subnet mask, IPv4/6 range, and the amount of usable IPs.
