section 7.9.2. Ethernet name resolution (MAC layer) gives the following order: IP address, ethers file entry, manuf file entry.

Assume: View/Name Resolution/Resolve Physical Addresses is selected.

My question is, if the user provides the ethers, which can be built with mac address to a common name (as shown in the example), why would they even want mostly ip addresses? Another way to ask this question is why isn't the resolution order: ethers file entry, IP address, manuf file entry? If the user doesn't provide an ethers file, then they get ip addresses, mostly, and manuf file entries for packets like ARP. If they go to the trouble to provide the ethers file, then they get their common name unless their is no matching MAC, then IP address or manuf file entry? Isn't this more user friendly and useful?

To avoid repeating the discussion here, refer to the comments in Bug 14252 for answers to these questions.

In a nutshell, the answer is simply to disable the "Use an external network name resolver" preference found via Edit -> Preferences -> Name Resolution. Be sure to restart Wireshark after saving this preference due to Bug 15468.
