Every device directly connected to the Internet needs an IP address and all organizations will need IPv6 address space to dual-stack their services. According to this TMC report, specific adoption needs and considerations will vary, and requirements will be different for each organization, depending on their network setup and the services they have deployed.
“The issue is simple: IPv4 addresses are running out, and fast. The solution to the address depletion is IPv6. This seemingly endless number of addresses holds the future of the Internet, but it requires companies that use and distribute IP addresses to adapt their networks and systems to use IPv6.
“The American Registry for Internet Numbers, or ARIN (News – Alert), is the non-profit corporation that manages the distribution of Internet number resources (IPv4 and IPv6 address space and autonomous system numbers) in Canada, many Caribbean and North Atlantic Islands, and the United States. ARIN participates in trade shows and conferences around the region to educate and inform people about issues facing the Internet community, the most critical of which is the rapid depletion of IPv4 address space.”
