The American Registry for Internet Numbers (ARIN) board of trustees passed a resolution recommending that the Internet technical community migrate a new version of the Internet Protocol, IPv6 will be needed to allow continued growth of the Internet.

The current IP version 4 (Ipv4) has over four billion unique IP addresses, which is not enough to last indefinitely. Ipv6 has more IP addresses and enhanced security features. ARIN has done technical coordination of both versions but has not endorsed one over the other.

There is just 19 percent of Ipv4 address space remaining and the ARIN says that the migration to Ipv6 is required for any applications that need to have ongoing availability of contiguous IP number resources.

"We must prepare for IPv4's depletion, and ARIN's resolution to encourage that migration to IPv6 may be the impetus for more organizations to start the planning process," said John Curran, Chairman of ARIN's Board of Trustees.
