c# calculate start and end by subnet code example

Example: c# calculate start and end by subnet

uint ip = "192.168.56.3".ConvertFromIpAddressToInteger();
 uint mask = "255.255.254.0".ConvertFromIpAddressToInteger();
 uint maskbit = "255.255.255.255".ConvertFromIpAddressToInteger();

 uint reverstmask = mask ^ maskbit;
 Console.WriteLine($"Reverse Mask :{(reverstmask).ConvertFromIntegerToIpAddress()}");
 Console.WriteLine($"Start :{(ip & mask).ConvertFromIntegerToIpAddress()}");
 Console.WriteLine($"End :{(ip | reverstmask).ConvertFromIntegerToIpAddress()}");
