IP Address control

I was in need of an IP control. Strangely enough there is nothing solid in the forum and more strange I could not find anything on the net , just some gibberish examples that work at some features.
I did find a C# control but the code was over stuffed and extremely complicated for that matters and the control was on XAML, that, apparently, did not do it for me.

So I decided to write a simple IP Address control with simple code that everyone can understand.

I will be providing the solution.If you don't want the control and you just need the code you can copy paste everything but the override text declaration. that would need to be inserted manually.
You would also need to check the textbox control properties as some are changed from the original textbox.
The control is basically textboxes merged together, fine and simple, an the functionality includes the 0-255 numbers the dot,comma,arrows navigation with focus, numbers only and no spaces between.
Feel free to change anything, if you might want the spaces closer or change the events.
The solution is on VS2015 but as there is no over sophisticated coding, I supposed it will work with previous versions as well.

If you want to see the control before even bothering, the finished control looks like this:

Was there any reason why the MaskBox wouldn't suffice?

Yes.
That was the exact reason I did not use a masked textbox and did this one.
I can't remember exactly what was the issue as I really erased the whole idea from my mind the minute I saw that the masked textbox control was problematic, but i think it was either the navigation or the empty space or the masked chars or something similar.
If I where to show the code I'm using this control for, there are leftovers from a masked textbox that failed to suffice.
Also if you look at many topics, masked textbox has issues in general for this kind of implementation.
