The Internet has experienced a phenomenal increase of devices accessing the Internet. Because of this increase, IPv4 addresses are running out. The solution is for IPv6 to accommodate this increased demand by providing a much larger address space, along with improved traffic routing and better security.
Some of the major advantages of IPv6 are:
- Larger IP address space: IPv6 has 128-bit address space or 4 times more address bits compared to IPv4's 32-bit address space. This large address space will provide enough address space for many decades to come. In real terms, every residential or commercial customer will be able to receive more address space from TWC than the entire IPv4 address space contains – several billion IP addresses!
- Better security: IPv6 includes security in the underlying protocol. For example, encryption of packets (ESP: Encapsulated Security Payload) and authentication of the sender of packets (AH: Authentication Header).
- Consideration to real time: To implement better support for real-time traffic (such as videoconference), IPv6 includes a flow label mechanism so routers can more easily recognize where to send information.
- Plug and play: IPv6 includes plug and play, which is easier for novice users to connect their machines to the network. Essentially, configuration will happen automatically.
- Better optimization: IPv6 takes the best of what made IPv4 successful and gets rid of minor flaws and unused features
