Full disclosure – I am not a network engineer (I am sure those that are can easily tell!!) – I do spend a lot of time with some of the best out there however and something I learned the other day was that the v4 concept of Network Address Translation (NAT) was a “stop gap” intended to extend the lifespan of v4 space – it was not an end unto itself!!
Now, one might ask (for I did): what does that mean?
Well, imagine a world where all things connected on line had a unique IP address (v6 enables that) – this was, incidentally how internet was envisioned at first – that means no more setting up NAT, you’ll have point to point communications without having to alter packets with NAT – this means a “flatter” architecture to Internet at large, a faster internet and far more flexibility and ease of deployment…
What else have you seen that will be reset as v6 is adopted?
