What is the process of forwarding packets between different IP networks?

• A. Routing
• B. Default Route
• C. ARP
• D. IP Addressing

Answer: (A)

Forwarding packets between different IP networks is routing. Routers look at the destination IP address in each packet, consult their routing table to find the best next hop toward that destination, and forward the packet accordingly. This enables a packet to traverse multiple networks and routers to reach its final destination. Routing can be static (manually configured) or dynamic (using protocols like OSPF, EIGRP, or BGP that help routers learn reachability). This inter-network movement is different from ARP, which resolves IP addresses to MAC addresses within a single local network, and from IP addressing, which assigns addresses to devices. A default route is a special route used when no specific route exists for a destination, not the general process of forwarding between networks.
