- The computer has an invalid default gateway address.
- The cable is not connected properly to the NIC.

- Any host or user can get a public IPv6 network address because the number of available IPv6 addresses is extremely large.
- Because IPv6 has integrated security, there is no need to hide the IPv6 addresses of internal networks.
- 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 Internet.
