IPv6 by Mind Map: IPv6

1. What makes it better

1.1. vs IPv4

1.1.1. More IP addresses

1.1.1.1. 128-bit vs 32-bit

1.1.1.1.1. 2^32 = 4.3 billion

1.1.1.1.2. 2^128 = 340 undecillion

1.1.2. Easier Multicasting

1.1.2.1. Prefix allows for 2^32 routable groups

1.1.3. Simplified Headers

1.1.3.1. Removed unused fields

1.1.4. Extensible Headers

1.1.4.1. Additional fields can be added

2. Why it's not being used

2.1. Usage Rates

2.1.1. Delaying the inevitable

2.1.2. IPv6 Statistics. 22 5 2011. 31 5 2011 http://www.google.com/intl/en/ipv6/statistics/

2.2. Major infrastructure overhaul

2.2.1. Many devices are IPv4

2.2.1.1. Computers

2.2.1.2. routers

2.2.1.3. modems

2.2.2. Expensive

3. How to make the transition

3.1. Transition

3.1.1. Dual Stack

3.1.2. Tunneling

3.1.3. Protocol Translation

3.2. Deployment

3.2.1. Upgrade Everything

3.2.1.1. Usually not very effective

3.2.2. Work from the outside In

3.2.3. One thing

3.2.3.1. dependencies must also be changed
