Red Hat Enterprise Linux Receives Department of Defense IPv6 Certification

Red Hat Enterprise Linux 5.2 Meets DoD Conformance and
Interoperability Requirements
RALEIGH, N.C.--(Business Wire)--
Red Hat (NYSE: RHT), the world's leading provider of open source
solutions, today announced that Red Hat Enterprise Linux 5.2 has
received Internet Protocol Version 6 (IPv6) Special Interoperability
Certification from the Defense Information System Agency (DISA) in
accordance with the Department of Defense (DoD) IPv6 Master Test Plan.
The certification demonstrates Red Hat's ongoing commitment to meeting
the growing demands of government agencies and enterprises as they
adapt to the next-generation Internet.

The DoD IPv6 product certification program began as a mandate from
the DoD's CIO and Assistant Secretary of Defense for Networks and
Information Integration (ASD-NII) who targeted FY08 as a target IPv6
transition completion date for the DoD. The IPv6 Special
Interoperability Certification for Red Hat Enterprise Linux 5.2 was
conducted by the Joint Interoperability Test Command (JITC), which
evaluates vendor products and DoD systems as IPv6 Capable.

With the certification, Red Hat Enterprise Linux 5.2 has been
certified for the DoD's Unified Capabilities Approved Products List
(UC APL) for an IPv6 capable Host and Workstation and IPv6 capable
Advanced Server. The certification ensures that Red Hat Enterprise
Linux 5.2 meets the DoD's set of mandated requirements, appropriate to
its Product Class, necessary for it to interoperate with other IPv6
products employed in DoD IPv6 networks.

"Receiving the DoD's IPv6 capable certification serves as strong
validation of Red Hat's ability to deliver solutions that meet
demanding requirements," said Paul Smith, vice president of Government
Operations at Red Hat. "Our continued support of standards and
rigorous testing means that our federal government customers can
confidently and quickly transition to the next-generation Internet
with Red Hat Enterprise Linux."
