The network portion of the IP address is information that is used by the router to determine the path between the source and destination hosts. The two types of media that are useful for connecting two devices that are separated by a distance of 500 meters is 1000 BASE-TX and 1000 BASE-SX.
in general the router uses the network address to compare to the routing table. Specifically, on the internet, the Router looks up the destination IP address in the router table to determine where to route the packet.

It uses the MAC address, Media Access Control. Every packet sent from a computer contains its MAC address. The router stores this in its routing table. When it receives a packet with a destiation address of that MAC address, then it forwards it to that computer. This is called NAT, Network Address Translation. It uses the Destination IP address

The router pattern bit in networking devices is used to determine the path that data packets will take when traveling between different networks. It helps the router make decisions on how to forward the packets to their intended destination.
The router must determine if it has a path to another network or router that may be in the path of the destination. When that occurs, it tries to find the "best path" (least cost) route to the destination. It has to consult its routing tables for that.
The first router in the path to the destination network. The next hop router is the first (or next) router in the path to the destination network. Each router looks at the destination network in the packet, then consults the routing table to identify the next hop router to the destination network. The hop count identifies the numbers of routers in the path to the destination network. A default gateway router is a router that is used for packets used to external networks. Most routers do not have a default gateway setting, but instead use a default route setting which identifies the next hop router for all unknown networks.
The router will install both routes in the routing table and load balance between the two.

How does a router know of paths to destination networks? (Choose two.) • inspection of the destination IP address in data packets ARP requests from connected routers manual configuration of routes • updates from other routers DHCP information broadcasts updates from the SMTP management information base
