This is a C# component, so first of all create an UserControl class called IPAddress. This most commonly done within a ComponentLibrary project. Pull a GroupBox from the toolbox on to the component design form. We now have the IPAddress.cs class, a Designer.cs and a resource IPAddress.resx file. Now just substitute the code with that listed here.
The IPAddress component is a group box called IPGroup, inside of which we place four NumericalTextBox and three DotLabel components

The base 10 type is used with the range limited to 0 to 255. The alternative of hex input requires changing the NumericalTextBox properties. An IPAddress class is used for I/O of the parameters. Padding with 0 is used to ensure the text displayed is always 3 digits.
