What address is used to send packets that are destined for an outside network?

The administrator would identify which address as the address to which all hosts send packets that are destined for an outside network?

10.10.10.6

What would the router do with packets destined to 192.168.254.254?

The router will use gateway of last resort IP address to forward packets destined to 192.168.254.254.

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.

When would a PC need a default gateway address?

You would only need a default gateway address if you wanted to route packets outside your local area network.

Which IP address processes enables workstations to use private IP addresses to access the Internet?

NAT (Network Address Translation) A service that translates a private IP address to a public IP address in packets destined for the internet, then translates the public IP address in the reply to the private address.

Is the default gateway address a portion of the destination IP address?

No, it is not. A destination IP address may be any address, usually on a completely different network. The default gateway address is used to determine where to send packets that need to be routed outside of the current local area network.

Define public address and private address?

A public address is one that is seen on the Internet and can be routed. A private IP address is only visible within its organization network and any packets containing a destination address using a private address will not be routed outside the organization.

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 is the gateway on my computer?

The default gateway refers to the "next-hop address"; the server or router your computer has to send packets to, to connect with the outside world. If the default gateway is not configured correctly, the usual symptoms are that your computer can connect within the local network, but it can't connect to the outside.You have to obtain the address which you should assign as the default gateway from your network administrator, or from your ISP.The default gateway refers to the "next-hop address"; the server or router your computer has to send packets to, to connect with the outside world.

Which defensive measures can you take to mitigate the possibility that your network could be used in this type of attack?

1. Filter packets leaving your network with source addresses that do not originate inside your network. 2. Filter packets entering your network with a broadcast address for a destination

What is antispoofing?

Using spoofing, an intruder can fake the source address of his packets and make them look like they originated on the trusted hosts.The basic idea of anti-spoofing protection is to create a firewall rule assigned to the external interface of the firewall that examines source address of all packets crossing that interface coming from outside. If the address belongs to the internal network or the firewall itself, the packet is dropped.

What part of the network layer address does the router use during path determination?

routers work at layer 3 (network) which usually means TCP/IP. Routing decisions are made based on a packets DESTINATION IP address.
