Auto Configuration

IPv6 uses a 128 bit address space
That is about 340,282,366,920,938,000,000,000,000,000,000,000,000 addresses

IPSec provides
Encrypted transport
Certificate based authentication

IPv6 provides global multicast support. If you can route to it you can multicast to it!

IPv6 has the ability for entire subnets to move from one router to another router without needing address re-assignment

TTL is now a hop count rather than time based for simpler calculation

IPv6 uses a fixed length subnet mask. All Subnets are /64 
Simplified packet header.
This facilitates efficient routing
No header checksum to calculate
-Link layer and higher layer checksums are relied upon for header integrity

Maximum transmit unit:

Path MTU Discovery
-Packet is sent using routers MTU, any router along the way that can not handle the packet sends an ICMPv6 packet to big message back with its MTU

Routers do not fragment IPv6 Packets
Maximum packet size must be established prior to transmission
