I know it feels like it’s been running out for years. It has. Since 2011. But now it’s really really run out. The last /8 has been issued.
It’s taken 20 years of grovelling by some boffins who made the new protocol (which is not at all comparable with IPv4) to get everyone to agree to switch.
So, who’s switched? Not many people. Of the top 1,000 websites in the world in terms of traffic, only 26.3% have switched. Why? I guess they just can’t be bothered.
Given the choice of doing something or doing nothing, most people prefer to do nothing. Even though it is wholly inevitable we’ll all have to switch and it is obvious the longer we leave it, the harder it is going to be to sort out. Kinda like ignoring parking tickets until you get taken to court.
So, farewell then, IPv4. At some point. Maybe 2021. Maybe not.
