Over the years I have had the luck to work alongside many really smart, switched on people in the development community. I’ve learnt from them many intermediate and experienced programming skills. Generally when it comes understanding the very basis of how the internet functions using DNS, most of these very same experienced developers haven’t got a clue. I wrote this post to hopefully help pay back some of the awesome karma they  have earned helping me over the years, by teaching them something in return. Lets learn about DNS.
