Why is NAT not needed in IPv6? 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. Any host or user can get a public IPv6 network address because the number of available IPv6 addresses is extremely large.

Which destination address is used in an ARP request frame? 0.0.0.0 255.255.255.255 the physical address of the destination host FFFF.FFFF.FFFF AAAA.AAAA.AAAA
FFFF.FFFF.FFFF The purpose of an ARP request is to find the MAC address of the destination host on an Ethernet LAN. The ARP process sends a Layer 2 broadcast to all devices on the Ethernet LAN. The frame contains the IP address of the destination and the broadcast MAC address, FFFF.FFFF.FFFF. The host with the IP address that matches the IP address in the ARP request will reply with a unicast frame that includes the MAC address of the host. Thus the original sending host will obtain the destination IP and MAC address pair to continue the encapsulation process for data transmission.
