3.1.6
ARP (Address Resolution Protocol)
In each TCP/IP-capable computer, ARP serves to clearly assign the worldwide unique hard-
ware addresses (MAC-IDs) to the single IP addresses of the network nodes via internal tables.
Using ARP in the DOS-prompt, every node in a network can be clearly identified via its MAC-
ID.
• Write a ping command for the respective station/ IP address:
(example: "x:\\ping 192.168.1.100").
• Via the command "x:\\arp -a" the MAC-ID for this IP address is determined. This MAC-ID
clearly identifies the network node.
3.1.7
Transmission media
For a communication via Ethernet, different transmission media can be used (see Chapter
8.1.4, Page 150).
