Long time ago, there was a networking protocol called ipv4 which drove the internet and everybody was happy.
Everybody?
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 work, it wasn’t possible for my car to have a facebook account to like 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 „all-ones“!
