convert ipnumber

I have 2 datagridview(same). I want to transform 2.datagridview to ipnumber from ipadress with this code piece;

long result = 0;
            if (!string.IsNullOrWhiteSpace(ip))
            {
                string[] temp = ip.Trim().Split('.');
                if (temp != null && temp.Count() > 3)
                {
                    string[] lastPart = temp[3].Split(':', ',', ' ');//Port verisinin gelmesi durumunda portu ayirmak için kullaniyoruz
                    result = long.Parse(temp[0]) * 256 * 256 * 256 +
                               long.Parse(temp[1]) * 256 * 256 +
                               long.Parse(temp[2]) * 256 +
                               //long.Parse(temp[3]);
                               long.Parse(lastPart[0]);
                }
            }

Hi Fatih,

You want to transform an ip address to an ip number in your second datagridview using the code you presented to us. Correct?

If that’s correct, what is stopping you from using your code to transform the data?

If you already have the answer (your code) to your question (transform an ip number to ip address), then what is the problem to be solved?

I have a question: What is the difference between an ip address and an ip number?

If I google ip number nothing comes up stating “ip number”. Instead google shows me everything ip address. What is the difference?
