Assuming that your text box contains complete IP addresses: "n.n.n.n" then the first thing to do is convert them from strings to IP addresses you can work with. There is a .NET method for this: IPAddress.Parse Method[^]

string s = "1.1.1.2";
IPAddress i = IPAddress.Parse(s);
byte[] bytes = i.GetAddressBytes();
for (int count = 0; count < 5; count++)
    {
    bytes[3]++;
    i = new IPAddress(bytes);
    Console.WriteLine(i.ToString());
    }

Hi,

Thanks to OriginalGriff for the part, the complete / dynamic solution would be:

C#

string address1 = "192.168.1.1";
string address2 = "192.168.5.254";

IPAddress startAddress = IPAddress.Parse(address1);
IPAddress endAddress = IPAddress.Parse(address2);

byte[] startAdrArr = startAddress.GetAddressBytes();
byte[] endAdrArr = endAddress.GetAddressBytes();

for (byte octet1 = startAdrArr[0]; octet1 <= endAdrArr[0]; octet1++)
{
	for (byte octet2 = startAdrArr[1]; octet2 <= endAdrArr[1]; octet2++)
	{
		for (byte octet3 = startAdrArr[2]; octet3 <= endAdrArr[2]; octet3++)
		{
			for (byte octet4 = startAdrArr[3]; octet4 <= endAdrArr[3]; octet4++)
			{
				string currentAddress = string.Format(
								CultureInfo.CurrentCulture,
								"{0}.{1}.{2}.{3}",
								octet1,
								octet2,
								octet3,
								octet4);
				/* process the address */
			}
		}
	}
}

Hope this helps anyone :)

Best regards and happy coding,
Stops
