I always get confused with Ethernet vs. IP headers.

It's definitely the destination address of the IP header!

I thought it was the destination address too, but I keep mixing it up with Ethernet header details from other questions.

I feel like it could also involve the source address, but I can't recall if that's relevant for routing decisions.

I remember practicing a question like this, and I think it was definitely about the destination address of the IP header.

I think we need to look at the destination address of the IP header, but I'm not completely sure if that's the only thing we compare.

Okay, let me see here. The key is to remember what information the router uses to forward unicast packets. I think I've got this.

Destination IP address, that's my best guess. I'll mark that and move on to the next question.

The key here is to focus on the information that routers use before forwarding unicast packets. I think the destination IP address is the most relevant.

I guess option A could work if it was a source-based routing scenario, but in a typical unicast forwarding case, it's all about the destination IP, baby!

Lol, option E? Seriously? The inbound port? That's just silly. Routers care about the IP destination, not the physical port.

I'm going with option C. The destination IP address is definitely the key information the router compares to make its forwarding decision.

Exactly, it helps the router determine the next hop for the packet.

Yeah, that's why the destination address of the IP header is compared with the routing table entries.

I'm not sure, but I think it might also be A) The source address of the IP header, to ensure the packet is coming from a valid source.

Hmm, the destination address of the IP header seems like the logical choice here. That's what the router uses to look up the appropriate path in the routing table.
