What is IPv6 Networking

Post on 1.29.11 by Dr. Paul Banes, with Cloud Providers Finders, Randolph, Mass.

What's all this about IPv6 vs IPv4?

IPv6, as the new backbone of the Internet, this new protocol will rectify the most difficult problems that the Internet faces today--scalability and management. And even though IPv6's implementation has met with some resistance over the past few years, all signs are now pointing to its gradual worldwide adoption in the very near future.

Sooner or later, all network administrators will need to understand IPv6, and now is a good time to get started......................

We cover in this training session some of the good current IPv6 videos...for free....enjoy

Unfortunately, number of available Internet addresses is now nearly full (all taken!), due mostly to the explosion of commercial websites and blogs and new sites from an expanding number of countries....especially India!

This always increasing and now dire shortage has basically put the Internet global users--and some of its most effective scientists--very watchful last decade.

Their solution was to create IPv6, a new Internet standard which will in the near future replace the current and outdated IPv4.

As we all know, the usage of the Internet has been growing VERY VERY fast, especially over the past couple years.

Information transfer is all important now, with more and more people getting onboard the World Wide Web and an enormous number of gadgets also becoming Internet enabled.

The Internet Protocol (IP) is the method (in technology, we call it "protocol") by which data is transmitted from one computer to another on the Internet. So every computer has a unique address (in computer world, this is called the IP address) and data is sent in packets of information from the sender's IP address to the receiver's, traversing many other points along the way.

We at Clear Cloud Network are seeing to the new developments and will report to the current Cloud Computing community in frequent intervals..

Thankfully, the current addressing scheme for IPv4 accurately delivers information to these houses.

Now imagine that the community has increased many fold and there are no available addresses (i.e. number) to identify houses in this larger community.

This is similar to what is happening with the explosive growth of the Internet, this system imposes a limitation on the number of possible IP addresses and could result in stalling the growth of the Internet in all its aspects. The new addressing system IPv6 is based on a 128-bit which vastly enhances the number of addresses.

Experts have made it clear that a gradual transition to the new protocol is inevitable. In fact, countries like India and Thialand have made rapid progress in launching IPv6.

The main ingredient TCP/IP Protocol:

TCP/IP (Transmission Control Protocol / Internet Protocol) is a suite of protocols. The suite consists of a layered set of protocols, with each layer building upon the layer below it, for a new functionality. At its lowest level, the protocol relates to the sending and receiving of raw data, while at the top, the protocols are concerned with file transfers or email delivery.

Routing and reliability are taken care of by the layers in-between.

The layered system makes it possible to add on new protocols for every new network application or hardware that needs to be introduced.

Why IPv6 is better than IPv4:

The following advantages are immediately obvious in the new scheme of things:

Larger address space
Support for mobile devices
Simplified address auto-configuration
Improved address management
Built-in security with end-to end IP Sec
Enables more levels of hierarchy for route aggregation (Route aggregation on the Internet is similar to the ZIP code system used by the postal department. For e.g., mail addressed with ZIP codes 9xxxx are directed to the West coast. Regional and local post offices on the West coast then sort the mail by looking further into the ZIP code. For example, 98xxx letters are sent to Washington while 97xxx letters are sent to Oregon.)
Makes it possible to upgrade functionality as needed, e.g., multicasting, QoS and mobility features. Quality of Service (QoS) is a technology that helps ease the congestion in packet-switched networks. QoS provides for network traffic to be divided into different classes during times of congestion, and helps in prioritizing information transfer.
On the IPv6 platform, billions of new devices such as cell phones, PDA's, appliances and even cars can be IPv6 enabled;
The Internet can extend its reach to billions of new users in densely populated regions of the world;
The protocol makes it possible for "always on" access technologies like xDSL, Cable or Ethernet connectivity.
