@Angie Much appreciated for the quick response Angie. I'll probably keep digging through my books for now as I hope to attain this before the next 6 months. I shall keep my eyes peeled for the courses though. Thanks!

Thank you for pointing that out and you are absolutely correct. When I said that, I didn't mean to imply that 20 was the only thing that it could start with, but that anything with a 20 at the beginning falls within the publicly registered range. If you get a publicly registered address today it will most likely start with 20 since that is the range they are issuing from, but in the future you very well may see all the way through 3f. In hind sight, I can see how that statement was confusing and I should have worded it differently.
Thanks again,
