Infoblox upgrades DNS appliances to ease move to IPv6

By , Network World |  Networking, DNS, Infoblox

Infoblox is adding two new features to its DNS appliances to help its service provider and enterprise customers transition to IPv6, the long-anticipated upgrade to the Internet's main communications protocol.

Infoblox officials said demand for these features -- including support for Dynamic Host Configuration Protocol (DHCP) for IPv6 and a translation technology called DNS64 -- is growing among wireless carriers, government agencies, universities and early adopters in the e-commerce space.

Infoblox has supported basic features of IPv6 since 2006.

The Infoblox announcement comes one day after OpenDNS announced the availability of a free IPv6-based DNS service for IT professionals who want to experiment with this next-generation Internet technology.

Infoblox IP Address Management (IPAM) tools help network administrators cope with the 128-bit addresses in IPv6, which are significantly larger than the 32-bit addresses used in IPv4, the current version of the Internet Protocol.

Infoblox's customers are starting to deploy IPv6 because the Internet is running out of IPv4 address space.

IPv4 can support only 4.3 billion devices connected to the Internet, and most of those addresses have been handed out. The free pool of unassigned IPv4 addresses was depleted in February, and the Asia Pacific regional Internet registry said in April that it has doled out all but its last 16.7 million IPv4 addresses, which are being held in reserve for startup network operators.

BACKGROUND: Asia out of IPv4 addresses

IPv6, on the other hand, uses 128-bit addresses and supports a virtually unlimited number of devices -- 2 to the 128th power. But despite its promise of an endless supply of address space, IPv6 represents only a fraction -- less than 0.03% -- of Internet traffic.

Infoblox said it is the first DNS appliance manufacturer to support DNS64, which is used by service providers and other network operators to bridge between IPv6 networks and legacy IPv4-only networks.
