What Wireshark feature maps MAC addresses to hardware manufacturers?

• A. Ignore MAC Addresses
• B. Resolve IP Addresses
• C. Resolve Physical Addresses
• D. Show Hardware Manufacturer Names

Answer: (C)

MAC addresses are the hardware identifiers used at the data link layer. Wireshark can look up the first part of a MAC address, the OUI, in the IEEE vendor database and display the corresponding hardware manufacturer. This capability is called resolving physical addresses, and it’s what lets you see manufacturer names next to MACs in the capture.

So the feature maps MAC addresses to hardware manufacturers by resolving physical addresses. The other options don’t fit because ignoring MACs would skip this mapping, resolving IP addresses deals with hostnames rather than MAC vendors, and showing hardware manufacturer names describes the result rather than the specific feature that performs the lookup.
