Secure64 Earns IPv6 Ready Gold Certification for all DNS and DNSSEC Products

Certification Critical for Products Purchased by U.S. Government Agencies and
International Markets

DENVER, May 19 /PRNewswire/ -- Secure64 Software Corporation today announced
the company has received IPv6 Ready gold certification from the IPv6 Forum for
its family of DNS and DNSSEC products.

IPv6 is the next-generation Internet Layer protocol for packet-switched
internetworks and the Internet. Many international markets have already
adopted IPv6. Within the U.S., the Office of Management and Budget issued a
mandate requiring federal agencies to be IPv6-enabled on their network
backbones by June 2008, and further recommending that agencies only procure
new IT products that are IPv6 compliant. However, the government has been
challenged by the lack of IPv6-enabled security devices and software
applications available in the commercial marketplace.

"Secure64 has strived from the beginning to be the 'gold standard' in DNS
software," said Steve Goodbarn, CEO and director of Secure64. "Achieving this
latest certification provides our federal and international customers with
even greater confidence that our DNS products are state of the art, while
providing the highest level of security and performance available."

History of Internet Protocol version 6 (IPv6)
IPv6 is the next-generation Internet Layer protocol for packet-switched
internetworks and the Internet. Internet Engineering Task Force (IETF)
designated IPv6 as the successor to version 4 by the publication of a
Standards Track specification, RFC 2460, in December 1998.

The difference between IPv6 and IPv4 is the address space. IPv6 uses a 128-bit
address, whereas IPv4 uses only 32 bits. This expansion provides flexibility
in allocating addresses and routing traffic and eliminates the primary need
for network address translation. IPv6's 128-bit addresses can support a
virtually unlimited number of devices and also can provide additional security
and network management features to support mobile computing. IPv6 also
implements new features that simplify aspects of address assignment (stateless
address autoconfiguration) and network renumbering (prefix and router
announcements) when changing Internet connectivity providers thus making
Internet management and routing more efficient.

IPv6 was developed in order to address the shrinking number of remaining IPv4
addresses, which were predicted to run out in 2012. This would have prevented
more devices from being IP-enabled and capable of connecting to the Internet.
IPV6 offers an unlimited number of addresses and therefore supports continued
growth of Web-based computing and mobile devices.

About the IPv6 Forum
The IPv6 Forum is a worldwide consortium that provides technical guidance for
the deployment of IPv6. One of its key functions is providing certification of
IPv6-ready products that conform to IPv6 specifications, support the protocol,
and ensure interoperability with other IPv6 products and technologies. The
certification and IPv6 Ready Logo program is managed by a global team of
technical members of the IPv6 Forum, including equipment vendors, service
providers, academic institutions, IPv6 organizations, members from the TAHI
Project (Japan), the University of New Hampshire InterOperability
(UNH-IOL)(USA), IRISA/INRIA (France), European Telecommunications
standardization Institute ETSI (Europe), Telecommunication Technology
Association TTA (Korea), Beijing Internet Institute BII (China), ChungHwa
Telecom Labs CHT-TL (Taiwan) and Japan Approvals Institute for
Telecommunications Equipment JATE (Japan).

Secure64 DNS Products
Secure64's suite of DNS products includes Secure64 DNS Signer, a software
product that fully automates Domain Name System Security Extensions (DNSSEC)
key generation, key rollover, zone signing and re-signing processes. It
reduces deployment and administration costs while eliminating errors that can
cause domains to become unavailable. The software also scales to extremely
large, dynamic environments by safely keeping DNSSEC signing keys online while
providing incremental zone signing and extremely high signing performance.

The company's other DNS product, Secure64 DNS Authority, is an authoritative
name server software product that's available at all times - even during
network attacks or restarts. It delivers the availability and security
required in today's networks, without the cost and complexity of conventional
solutions.
