Infoblox Delivers IPv6 with DNS64

By Sean Michael Kerner May 4, 2011

With the free pool of IPv4 addresses now exhausted, enterprises and service providers are focusing on IPv6 . The migration to IPv6 is one that will likely take many years, which is why it's important to have support for both IPv4 and IPv6.

The new DNS64 enabled DDI (DNS , DHCP and IPAM) Gateway from Infoblox is one such solution targeted at helping the migration of IPv4 to IPv6. One of the requirements for deploying IPv6 is to have an IPv6 capable DNS server that handles AAAA records.

What happens, though, when a request comes in for content that is still connected via IPv4?

"DNS64 and NAT64 are technologies that enable people that are building out IPv6 networks to be able to let devices communicate with stuff on IPv4," Cricket Liu, Infoblox vice president of Architecture and Technology told "For the time being most websites and mail servers you want to reach will all be on IPv4."

DNS64 provides a translation layer for the AAAA record into an IPv4 A record and vice versa.

Liu noted that Infoblox just provides the DNS64 component and not NAT64. He added that NAT64 is delivered by inline device vendors. One such networking vendor is Brocade which recently added NAT64 capabilities to it ADX load balancer.

Infoblox has a set of appliances that delivers DDI services running the Infoblox NIOS software. Liu noted that the core underlying operating system is a stripped down version of Linux, though he added that Infoblox is able to take advantage of some of the IPv6 capabilities in Linux.
