February 01, 2011, 4:19 PM — Juniper Networks is accelerating its plan to support IPv6 on its public-facing Web site and Web services, following criticism that the router maker was lagging rivals including Cisco Systems and Brocade Networks in this critical area.

JUNIPER CRITICIZED: Juniper defends poky pace on IPv6-enabling its Web site
IPv6 is the long-anticipated upgrade to the Internet's main communications protocol, which is called IPv4. IPv6 is a necessary upgrade for Web site and network operators because the Internet this week ran out of address space using IPv4.
IPv4 uses 32-bit addresses and can support 4.3 billion devices connected directly to the Internet. IPv6, on the other hand, uses 128-bit addresses and supports a virtually unlimited number of devices -- 2 to the 128th power.
BYE, BYE: IPv4 addresses gone
In November, Juniper said that it would support IPv6 traffic on its main Web site by September 2012, the same date that Web sites operated by U.S. federal agencies are required to support IPv6.
Also in August, Cisco set up a special-purpose IPv6-only Web site and said it was experimenting with techniques for supporting IPv6 on its main Web site in 2011.
With pressure mounting for network vendors to deploy the IPv6 products that they are selling to carriers and enterprises, Juniper said it has made IPv6-enabling its Web site a higher priority.
