IPv6 Features
Larger Address Space
With four times more bits than its predecessor, IPv6 is capable of providing address space for approximately 3.4*10^38 devices.
Simplified Header
IPv6 has a simplified header format that is designed to be less complex and easier to process than IPv4.
End-to-End Connectivity
With IPv6, every machine is able to access the internet without requiring NATs or other translating elements.
Faster Forwarding or Routing
Faster routing decisions are possible with IPv6 due to the streamlined header that places all extra information at the end.
Stronger Security Through IPSec
Internet protocol security makes IPv6 more secure than IPv4 and it is used at the network processing layer.
Greater Mobility
Devices are able to remain connected to the same IP address even when roaming in different locations with the help of automatic IP configuration and extension headers.
Scalability
IPv6 provides room for scalability by adding extension headers.
