This is a helper function to convert a subnet mask written as an IPv4 address to its equivalent suffix.
function subnetSuffix(mask) { if (mask) { return mask .split(".") // ["255", "255", "255", "0"] .map(i => (i >>> 0).toString(2)) // ["11111111", "11111111", "11111111", "0"] .join("") // "1111111111111111111111110" .replace(/0/g, "") // "111111111111111111111111" .length // 24 } return 0; } subnetSuffix("255.255.255.0"); // 24
