According to the American Registry for Internet Numbers (ARIN), which manages the distribution of Internet numbers resources for the US, Canada, and much of the Caribbean and North Atlantic, the Internet is running out of space — IPv4 space that is. Many sources have been talking about the eventual exhaustion for years. But only recently is it getting significant press. Representatives of ARIN are acting diligently to spread awareness of the problem, and what can be done about it.
Less than 3% of IPv4 space remains so we could reach the end any day now.
