Tech experts agree that the explosive internet growth we see today was unexpected. Many business owners are still trying to cope up with the increase of internet enabled devices and the challenges they bring along. Many of us are also aware that IPv4 address spaces were on the verge of exhaustion a few years ago.

When a large company like Microsoft starts admitting some globally occurring challenges, you know the problem is real. In a conference in 2015, a network expert from Microsoft, when asked about the IPv4 exhaustion, said even the company has been having a hard time coping with it.

The time is here. IPv4 addresses have been completely exhausted. ARIN is all out of stock. The software and hardware costs to migrate to IPv6 are still impractical. Despite being introduced in 1998, IPv6 address blocks are still expected to take another decade before they are deployed completely. Meanwhile, the exhaustion of IPv4 address blocks has given birth to a secondary market that helps companies buy and sell them.
