A host has just booted up. This host is allowed to send ARP queries for the MAC address of thelocal DNS server before sending gratuitous ARPs to test for duplicate IP addresses on the network.

You may need to capture traffic at different points on the network to identify the location of packet loss.

Wireshark's GeoIP feature launches an OpenStreetMap view of the world from the Endpoints window to plot IP addresses seen in the trace file.

Some ICMP packets include portions of the original packet that triggered the ICMP response.

Which name resolution process translates port numbers to service names if they are listed in Wireshark's services file?
