Which of the following is a reason why IPv6 has been developed?
a. IPv4 addresses are not secure. /
b. IPv4 addresses are running out. /
c. Dynamic address allocation is desired. /
d. Mobile IP networking is needed.
What version of IOS do I need to run on a Cisco 3560 and 3550 to support IPv6?
Which routers are IPv6 enabled? Can anybody suggest me any IPv6 enabled routers?
Have you ever come to similar problems? With more netizen and faster development of internet, mobile internet, more and more people require a better enjoyment of surfing on the net and a higher internet security, we usually like to compare IPv4 with IPv6, often ask others that what IPv6 will bring to us?…
IPv6 is a new IP protocol mandated by the federal government for compliance across all organizations, it is designed to replace IPv4, the Internet protocol currently deployed and used most extensively throughout the world.
Comparison to IPv4
Pv6 specifies a new packet format, designed to minimize packet header processing by routers.
Advantages comparing to IPv4
Larger address space: The most important feature of IPv6 is a much larger address space than in IPv4. The length of an IPv6 address is 128 bits, but 32 bits in IPv4.
Multicasting: Multicasting (the transmission of a packet to multiple destinations in a single send operation) is part of the base specification in IPv6. In IPv4 this is an optional although commonly implemented feature.
Stateless address auto configuration (SLAAC): The packet header in IPv6 is simpler than that used in IPv4. IPv6 routers do not perform fragmentation…
Mobility: IPv6 routers may also support network mobility which allows entire subnets to move to a new router connection point without renumbering.
The benefits of IPv6 include:
Simplified packet header for routing efficiency
Mandatory IP Security (IPsec) implementation for all IPv6 devices
Improved support for mobile IP and mobile computing devices
Enhanced multicast support with increased addresses and efficient mechanisms
Talk to CISCO: Why You Need IPv6 Now?
CISCO: The Internet is changing and developing fast, mobile internet is a new hot trend today.
By the end of 2011, there will be no more IPv4 addresses. New customers and Internet traffic will be using the next-generation Internet protocol: IPv6. The accelerating growth of the Internet presents powerful opportunities to transform the way we work, live, play, and learn.
Cisco IPv6 solutions can help your organization extend its reach and harness the power of the growing Internet. Based on your industry, we can help you maximize the value of your existing investments while you prepare for the next wave of Internet growth.
Education: Integrate IPv6 into the IPv4 infrastructure at your educational institution.
Enterprise: Learn how Cisco Services can help you plan a smooth IPv6 transition.
Federal: The federal government has mandated compliance with IPv6 across all organizations. See how other agencies are making the change and how Cisco can help with your transition.
Service Provider: The Cisco Carrier-Grade IPv6 Solution (CGv6) helps service providers maintain and continue to accelerate growth.
Small Business: Prepare your small business to take advantage of the growth of the Internet.
For many years, experts have predicted the exhaustion of the IPv4 address space. Technologies like address translation have enabled most organizations to defer their IPv6 plan. But with address space exhaustion looming, now is the time to plan for this critical transition.
Unlike many past technologies, IPv6 does not have a defined ROI. However, the price of inaction is high: lost customers reduced global reach, and unplanned, reactionary expenses.
Make the Transition: Cisco has been investing in IPv6 innovations for over 10 years. Bring the power of that investment to your organization’s plan with Cisco’s three general approaches:
Preserve by auditing your existing systems
Prepare by making a plan and starting a managed migration
Prosper through the transition to a full IPv6-enabled Internet
Cisco Services has helped large enterprises, government agencies, and some of the world’s leading service providers with IPv6. Start IPv6? Why not?
