What is the best way of validating an IP Address?

Question

I have a method to validate a parameter IP Address. Being new to development as a whole I would like to know if there is a better way of doing this.

Answer 1

The framework provides the IPAddress class which in turn provides you the Parse and TryParse methods.

// myAddress is a System.Net.IPAddress instance
if (System.Net.IPAddress.TryParse(strIP , out myAddress)) 
    // IP is valid
else
    // IP isn't valid
