Is there currently a formula for calculating the network ID when you know the amount of networks used?

**edit: I wanted to mention the reason I am asking is because I have scoured the internet to find a formula similar** I figured a formula and wanted to know if such a formula is was already in use. (256/number of networks) * (desired subnet - 1) Edit: the use of 256 is one over the max number used in ip addresses. Edit: 256 isn't the largest possible network in the formula. It creates the decimal quotient used to predict the ip address for that subnet. If the result after the formula is a decimal then multiply that decimal by 255 aka the max number of ip addresses in an octet which will show the number for the next octet.
