Listen Up Soldiers

Thanks to IPv6, an entirely new command and control model is taking shape for federal agencies and the Department of Defense. While military requirements and systems are constantly in flux, IPv6 makes it possible to create ad hoc and expansive networks as well as attach an IP address to anything that has a CPU to enhance mobility, refine tactics and improve military strategy.

With IPv6, we can create network capabilities that better meet mission needs. IPv6 is clearly changing the game and arming our soldiers with better IT capabilities as we take on critical missions around the world.

Ubiquitous Connectivity

Ubiquitous Internet connectivity is no longer a dream with IPv6. In fact, countries like Korea are on the forefront of enabling ubiquitous IP connectivity for everyone by leveraging IPv6 support and network expansion capabilities. True peer-to-peer communication, multiple IP addresses, video exchange, Internet access for the entire population, and more functionality in a dynamic setting are all possible with IPv6.


In order to reach the IPv6 Internet, an isolated host or network must be able to use the existing IPv4 infrastructure to carry IPv6 packets. This is done using a technique known as tunneling which consists of encapsulating IPv6 packets within IPv4, in effect using IPv4 as a link layer for IPv6.

IPv6 packets can be directly encapsulated within IPv4 packets using protocol number 41. They can also be encapsulated within UDP packets e.g. in order to cross a router or NAT device that blocks protocol 41 traffic. They can of course also use generic encapsulation schemes, such as AYIYA or GRE.
