ARP techniques (contd)
2: Table Lookup: Searching or indexing to get MAC addresses
- Similar to lookup in /etc/hosts for names
- Problem: change Ethernet card => change table
3. Dynamic Binding: ARP
- The host broadcasts a request: “What is the MAC address of 127.123.115.08?”
- The host whose IP address is 127.123.115.08 replies back: “The MAC address for 127.123.115.08 is 8A-5F-3C-23-45-5616”
All three methods are allowed in TCP/IP networks.
