When you send a packet to a host in a remote network the packet is forwarded to where?
When you send a packet to a host in a remote network, the packet is first forwarded to the default gateway of your local network. From there, the gateway routes the packet through various intermediary routers across the internet, using the destination IP address to determine the best path. Ultimately, the packet arrives at the target host's network, where it is directed to the specific device intended to receive it.

What are true statements about routes and their use?
--> If the destination network is directly connected, the router forwards the packet to the destination host. --> If no route exists for the destination network and a default route is present, the packet is forwarded to the next-hop router. --> If the originating host has a default gateway configured, the packet for a remote network can be forwarded using that route.
Can a packet be forwarded without a route?
No packet can be forwarded without a route. Whether the packet is originating in a host or being forwarded by an intermediary device, the device must have a route to identify where to forward the packet.
What action is taken by a host on an Ethernet network when the host attempts to contact a remote host on another network?
The packet is sent using the IP address and MAC address of the default gateway.
Why does wireshark shows the actual MAC address for the local host but not for the remote host?
Wireshark displays the actual MAC address of the local host because it is directly connected to the network and can access its own hardware address. In contrast, for remote hosts, Wireshark typically shows the MAC address of the last device that forwarded the packet, such as a router, instead of the actual MAC address of the remote host. This is due to the way Ethernet and IP networking function, where MAC addresses are only visible within the same local network segment.
A subnet mask separates?
A submask is designed to separate the network id portion of an IP address from the host or client portion. This helps a router determine whether the packet needs to be forwarded to another network.
How will a packet that is sent from host A to host B be handled by the devices on the network?
C
If a remote host can be pinged what problems can you rule out?
If a remote host can be pinged, you can rule out basic connectivity issues between your device and the remote host, such as network disconnection or a downed remote server. It also suggests that the host's firewall is not blocking ICMP packets, allowing for successful communication at the network layer. However, this does not rule out application-layer issues, such as problems with specific services or ports on the remote host.
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.
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.
What does the local host use to determine the destination network ID of a particular packet?
the address Class
Why Network virtual terminal is needed in remote login?
Network Virtual Terminal, is a software version of a physical terminal and allows a user to log on to a remote host .So the application created emulation of terminal at the remote host .Users computer talks to the software terminal which in turn talks to the host & vice verse .Remote host believes it is communication with one of its own terminals and allow you to log on
When a host doesn't receive a packet describe what happens?
When a host does not receive a packet, it typically triggers a timeout mechanism, prompting the host to retransmit the packet after a specified period. In protocols like TCP, this may lead to an increase in the retransmission timeout (RTO) to avoid overwhelming the network. Additionally, if packet loss is detected, the host may implement congestion control measures to manage data flow. Ultimately, the failure to receive a packet can impact overall communication efficiency and reliability.
