<P> IPv4 address exhaustion is the depletion of the pool of unallocated IPv4 addresses . Because there are fewer than 4.3 billion addresses available , depletion has been anticipated since the late 1980s , when the Internet started to experience dramatic growth . This depletion is one of the reasons for the development and deployment of its successor protocol , IPv6 . Currently IPv4 and IPv6 coexist in the Internet . </P>
