Which addressing type is used to route information between networks?

• A. Network or Logical Addressing
• B. MAC Address
• C. Subnet Mask
• D. Port Addressing

Answer: (A)

Routing information between networks relies on network or logical addressing. This is the addressing that routers use to understand where a packet should go beyond the local segment. In IP networks, addresses identify the destination across multiple networks, allowing routers to inspect the destination address and forward the packet toward its next hop toward the final network. MAC addresses, by contrast, are hardware identifiers used within a single local area network to deliver frames between devices on the same broadcast domain. The subnet mask helps determine which portion of an IP address identifies the network versus the host, aiding decisions about on-link versus off-link delivery, but it doesn’t route packets by itself. Port addressing identifies specific applications on a host and operates at the transport layer, not for routing between networks. So the ability to route across networks comes from network (logical) addressing.
