OARnet prepared for IPv6

Feb 3, 2011


IPv4 addresses still available

The international availability of Internet IPv4 address allocations (Internet Protocol version 4), is nearing an end. The Number Resource Organization (NRO), the Internet Corporation for Assigned Names and Numbers, the Internet Society (ISOC) and the Internet Architecture Board, made this joint announcement on February 3.

However, OARnet has several large allocations of IPv4 Internet addresses accessible for its members.

“More than half of the IPv4 addresses allocated to OARnet are still available for member use,” said Mark Fullmer, OARnet IP Services Manager. “Barring any unforeseen circumstances, we anticipate our members will be able to obtain IPv4 addresses from OARnet for a number of years.”

The long-term solution for IPv4 address space exhaustion is migrating to IPv6, an addressing system that uses more digits. In anticipation of the day when IPv6 addresses would become the standard, OARnet has acquired network space from the American Registry for Internet Numbers (ARIN) sufficient to meet the needs of all clientele. Currently, OARnet is already running a dual stack IPv6 network. Members interested in IPv4 or IPv6 address allocations from OARnet for their organizations should contact the Network Operations Center at 1-800-627-6420 or support@oar.net.
