How do I resolve name resolution in Wireshark?

Name resolution tries to convert some of the numerical address values into a human readable format. There are two possible ways to do these conversions, depending on the resolution to be done: calling system/network services (like the gethostname() function) and/or resolve from Wireshark specific configuration files.

How does Wireshark show hostname?

Open the pcap in Wireshark and filter on nbns. This should reveal the NBNS traffic. Select the first frame, and you can quickly correlate the IP address with a MAC address and hostname as shown in Figure 5. The frame details section also shows the hostname assigned to an IP address as shown in Figure 6.

Can Wireshark automatically resolve the IP address into host names?

Wireshark will resolve ip addresses to hostnames when the capture file contains DNS traffic or when you have a hosts file in your profile that maps ip addresses to hostnames. You can also 'Use an external name resolver' to resolve the IP addresses using your DNS when you open the trace file.
