When it comes to the network, I’m a selfish guy. I want to use my computer and phone anytime, from anywhere, and with anyone. I want it all and when it is convenient for me. I honestly don’t feel too bad about this selfish streak since everyone I know wants the same things from the network. Most people don’t care about problems that result from sharing the network – they just want unlimited and uninterrupted access.
To meet this need, the Internet, public services and many corporate networks are moving to IPv6, a newer version of basic IP protocol. Why is there such a need to change when the existing standard, IPv4, is still running our networks just fine? Well, quite frankly, the world is running out of IPv4 addresses. Current fixes to share IPv4 addresses among users and devices cause performance, scalability and reliability problems as new devices and new video, voice, and collaborative applications become pervasive.
What’s the difference between IPv4 and IPv6?
First and foremost IPv6 extends the number of addresses significantly. The Internet, based on the venerable IPv4 packet format, has been burning most of the available addresses (roughly 4 billion) in its first 25 years of existence. IPv6 enhances the length of the address field from 32 bits to 128 bits, resulting in enough addresses to cope with the growth of the Internet for centuries to come, and enabling true borderless connectivity (anybody, anything, anywhere, anytime).
