oharsta / IPvXPrefixCalculator.scala

Last active August 29, 2015 14:07

Calculate the addition of IPv4 and IPv6 prefix lengths (e.g. a IPv4 /23 and a /23 result in a /22)

	object PrefixCalculator {

	def sumIpv4(ipv4Prefixes: Seq[Int]) : Int = doSumIpvX(ipv4Prefixes, 32)

	def sumIpv6(ipv6Prefixes: Seq[Int]) : Int = doSumIpvX(ipv6Prefixes, 128)

	private def doSumIpvX(prefixes: Seq[Int], bitSize: Int) : Int = {
	val addressSize = prefixes.map(prefix => Math.pow(2, bitSize - prefix)).sum
	(bitSize - (Math.log(addressSize) / Math.log(2))).floor.toInt
	}
