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.
