Advantages:
- Provides more address space ( which is being needed in larger buisness scales-example comcast)
- More powerful internet (128bit versus IPv4's current 32 bit)
- Offers and overall larger scale internet-which again will be needed in the future
- Address allocation is done by the device itself
- Support for security using (IPsec) Internet Protocol Security
- It will be much harder to remember IP addresses (compared to the addresses now)
- Creating a smooth transition from IPv4 to IPv6
- IPv6 is not available to machines that run IPv4
- Any consumer costs in having to replace an IPv4 machine
- Time to convert over to IPv6
