vs IPV4

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
