We're running out of Internet addresses
Every place and device on the Internet is identified by a string of numbers knows as an IP address. It would be a pain to remember 216.35.221.77 to visit the National Public Radio site, so the Internet's domain name system translates those numbers into human-friendly names like "NPR.org."
But there's a problem with those numeric IP addresses: They're running dry.
Experts say the available pool of almost four billion addresses from the system known as IPv4 will be gone in three years or four years.
