  7. string strIP = "2404:6800:4001:805::1006";
  8. System.Net.IPAddress address;
  9. System.Numerics.BigInteger ipnum;
  10.  
  11. if (System.Net.IPAddress.TryParse(strIP, out address)) {
  12. byte[] addrBytes = address.GetAddressBytes();

  14. if (System.BitConverter.IsLittleEndian) {
  15. System.Collections.Generic.List<byte> byteList = new System.Collections.Generic.List<byte>(addrBytes);
  16. byteList.Reverse();
  17. addrBytes = byteList.ToArray();
  18. }

  20. if (addrBytes.Length > 8) {
  21. //IPv6
  22. ipnum = System.BitConverter.ToUInt64(addrBytes, 8);
  23. ipnum <<= 64;
  24. ipnum += System.BitConverter.ToUInt64(addrBytes, 0);
  25. } else {
