Long time ago, there was a networking protocol called ipv4 which drove the internet and everybody was happy.
Not everybody, unfortunately – my fridge for example had no access to the internet and was not able to order food when the forecast predicted low-food level. My washing machine couldn’t send an email when finishing the work, it wasn’t possible for my car to have a facebook account to communicate how much it liked empty highways without speed limit…
These issues have been solved with ipv6, ip next generation, the new foundation of the internet.
The broadcast-concept left the stage, too.
Never miss the broadcast – catch the frame with destination address allones!
