I would use

var ip = IPAddress.Parse(ipString);

IPAddress is in System.Net and already does what you want to do for you. You can use TryParse() if you want the boolean return value instead.

Try:

Regex ip = new Regex(@"\b\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}\b");
MatchCollection result = ip.Matches(getObj("TextPPPIPAddress0").value);
Console.WriteLine(result[0]);
