ARP is used to dynamically build and maintain a mapping database between link local layer 2 addresses and layer 3 addresses. In the common case this table is for mapping Ethernet to IP addresses. This database is called the ARP_Table.
Can Wireshark capture packets from other computers?
Note 2: LAN traffic is in broadcast mode, meaning a single computer with Wireshark can see traffic between two other computers. If you want to see traffic to an external site, you need to capture the packets on the local computer.
How ARP works step by step?
How does ARP work?
- The source device will broadcast the ARP request message to the local network.
- The broadcast message is received by all the other devices in the LAN network.
- The device whose IP address has matched with the destination IP address in the packet will reply and send the ARP Reply message.
Why ARP is needed?
ARP is necessary because the underlying ethernet hardware communicates using ethernet addresses, not IP addresses. Suppose that one machine, with IP address 2 on an ethernet network, wants to speak to another machine on the same network with IP address 8.
