3 Why is NAT not needed in IPv6? > 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 >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. ITN (Version 7.00) - Communicating Between Networks Exam 14 When transporting data from real-time applications, such as streaming audio and video, which field in the IPv6 header can be used to inform the routers and switches to maintain the same path for the packets in the same conversation?
