What else can I help you with?
What is the protocol responsible for locating a host on a local network?
ARP
What is responsible for discovering the internet address of a host on the local network?
RARP
How does ANDing help an originating host?
An originating host must determine if a packet should be sent directly to a host in the local network or be directed to the gateway.
Why do routers use anding?
ANDing is used by a router, to see if the host which has to be contacted, is on the local network of the router, or a remote network.
What do network host use data link layer addresses for?
Local delivery
The local host can send packets on the local network?
The localhost address is designed to verify that the software for networking has been installed and is operating correctly. It does not pass any packets to the network.
What does the local host use to determine the destination network ID of a particular packet?
the address Class
When DNS is installed on a server what service can DNS perform for users of client computers accessing network resources?
DNS stands for Domain naming system. it basicly translate ip address to host names and host names to ip address. If you use it on a local network it allows you to use your own naming conventions for your local subnet . Which helps to work easily in huge network need to remember only host names in network.
When a host on network A sends a message to a host on network B which address does the router look at?
When a host on network A sends a message to a host on network B, the router looks at the destination IP address in the packet’s header to determine where to forward the message. This IP address is used to identify the specific network and host within that network. The router uses its routing table to decide the best path for the packet based on this destination IP address. The MAC address is not used for routing between different networks, as it only applies to the local network segment.
Do packets that are sent to host on the same local network need to be translated?

What address is used by a local host when you need to forward packets to the host on a different subnet?
When forwarding packets to a host on a different subnet, the local host uses the address of the default gateway, which is typically a router within the same subnet. The default gateway serves as an intermediary that routes traffic from the local subnet to other subnets. This address is configured in the network settings of the local host. Packets destined for outside the local subnet are sent to this default gateway for further routing.
What is a possible reason that host a and host b are unable to communicate outside the local network?
Because they need a device to communicate with a distant network through. These devices are called gateways, and are normally routers. The hosts on a segment need to have knowledge of the gateway device in order to communicate outside the segment. In most environments, the local network will have an internal addressing scheme, one that is not routable on the internet, so there needs to be a device that can translate the internal addresses (non routable on the internet) into external addresses (routable on the internet). Of course this device needs to be connected to both the internal network and the external network to be able to send traffic between them.
