Why Is Nat Not Needed In Ipv6 Anymore?

The biggest issue I found in removing NAT is the reduction of privacy. With IPv6 I notice all my LAN devices have a unique public IPv6 address, which allows each device on a LAN to be identified uniquely. Which then allows easier identification of individual devices and users.

Privacy implications like the ability to track your activity across domains. Ad providers obviously do this type of tracking already with cookies, but removing NAT makes their job easier to track an individual device.

Why Is Nat Not Needed In Ipv6?

• Because IPv6 has integrated security, there is no need to hide the IPv6 addresses of internal networks.​
  
• Any host or user can get a public IPv6 network address because the number of available IPv6 addresses is extremely large.​
  
• The problems that are induced by NAT applications are solved because the IPv6 header improves packet handling by intermediate routers.​
  
• The end-to-end connectivity problems that are caused by NAT are solved because the number of routes increases with the number of nodes that are connected to the Interne
