Why

https://www.siliconrepublic.com/comms/why-ipv6-is-the-future-of-the-internet-retn-ipv4-protocol

  • allows for more efficient routing without fragmenting packets
  • longer life for network equipment due to better summarisation
  • lower latency
  • easier set-up and maintenance
  • greater cost-efficiency and performance
  • far larger address space and capacity
  • improved security
  • better network auto-configuration capabilities
