It’s official: North America is out of new IPv4 addresses

North America has finally run out of new addresses based on IPv4, the numbering system that got the Internet where it is today but which is running out of space for the coming era of networking.

The American Registry for Internet Numbers, the nonprofit group that distributes Internet addresses for the region, said Thursday it has assigned the last addresses in its free pool. The announcement came after years of warnings from ARIN and others that IPv4 addresses were running out and that enterprises and carriers should adopt the next protocol, IPv6.

IPv4 dates back to 1981 and only has room for 4.3 billion unique addresses. IPv6, introduced in 1999, should have enough addresses to serve Internet users for generations, according to ARIN.

Twitter confirms it’s experimenting with native polls in tweets

Twitter is looking at possibly letting users add quick polls to their tweets. A company spokesperson confirmed the move in a statement to VentureBeat saying, “We’re experimenting with a new way to poll users on Twitter.”

Right now, it looks like polls are only visible on Twitter’s mobile apps and website, but not on desktop applications like TweetDeck. There’s no indication of whether this capability will be rolled out to the rest of the 316 million monthly active users, as it’s an experiment that could wind up being shelved.

This isn’t the first time that Twitter has rolled out polls on its communications service. Previously, companies were able to poll their followers through custom card polls. In 2014, Twitter revealed that it was testing out a feature that would enable native ads for publishers. Today’s sightings may hint that these could be rolled out to a wider audience.

From what we’ve seen, all polls have a 24-hour time limit on them.

While Twitter declined to provide more information, a quick query on the site showed that at least Twitter employees and also some verified profiles, including those in the media and in sports, have access to embed these polls.
