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

try with this:

private bool IsValidIP(String ip)
    {
        try
        {
            if (ip == null || ip.Length == 0)
            {
                return false;
            }

            String[] parts = ip.Split(new[] { "." }, StringSplitOptions.None);
            if (parts.Length != 4)
            {
                return false;
            }

            foreach (String s in parts)
            {
                int i = Int32.Parse(s);
                if ((i < 0) || (i > 255))
                {
                    return false;
                }
            }
            if (ip.EndsWith("."))
            {
                return false;
            }

            return true;
        }
        catch (Exception e)
        {
            return false;
        }
    }
