Dear Kumar,
I have tried your code, but not working.
E.g.:
string strIPAddress = "244";
IPAddress Address;
if (IPAddress.TryParse(strIPAddress, out Address))
{
//Valid IP Address
}

This code is giving true but it should be false.
Can you help me.

If you give 244 it will assume like 0.0.0.244

Use the below code

string strIPAddress = "192.0.0.244";
IPAddress Address;
string[] strAddress = strIPAddress.Split('.');
if (strAddress.Count() == 4)
{
if (IPAddress.TryParse(strIPAddress, out Address))
{
//Valid IP Address
}
}
else
{
//please provide valid IP address
}

I understand, but if user pass 244 as an ip, then it is invalid. But your code is showing a valid one. So how to do this?
