Most of us know that eventually all of the current iPv4 addresses will run out and this will leave us with certain problems. The last iPv4 addresses were issued a few years ago and by now there is only a limited supply found mainly on the African continent. The next wave is going to be iPv6, this is the updated protocol and it is about time that we all started to look into the differences between iPv4 and iPv6. Luckily for us the people over at Irish Telecom have done some work on this subject and come up with a useful graphic. Now you have no excuses when you are ask about the differences between iPv4 and iPv6!
