Consumer and business user's consumption for IP-based devices (mobile phones, laptops and servers) are increasing the demand for both IPv4 and IPv6 address space.
According to the Number Resource Organization's (NRO) Q1 2010 Internet Number Resource Status Report, the allocations of IPv4 address in Q1 have reduced the IANA free pool of IPv4 addresses to 8.5 percent. At the same time, APNIC, the Regional Internet Registry (RIR) for Asia Pacific, allocated nearly 27 million IPv4 address to its members, one of the largest allocations any RIR has made in one quarter. What's more, APNIC issued 186 IPv6 allocations in Q1 2010.
Going forward, the obvious concern for service providers, consumers, vendors and businesses is the oncoming migration to IPv6 and the depletion of IPv4 addresses. It is estimated that in a year and a half there will be no more IPv4 addresses left so the IP industry needs to continue mapping out an IPv4 to IPv6 migration process.
