How to ARP ping?

Published in ARP Configuration 2 mins read

The provided information describes a method that simulates an ARP ping, not a true ARP ping. True ARP pings don't use the ICMP ping utility. This method manually adds an ARP entry and then uses the standard ping command with a specific packet size.

Here's a breakdown of how to perform this simulated ARP ping:

Steps to Simulate an ARP Ping

  1. Add a Static ARP Entry:

    • Open the Command Prompt as an administrator. You can do this by opening the [Start] menu and selecting [All Programs] or [Programs] [Accessories] [Command Prompt].

    • Use the arp -s command to create a static ARP entry. The syntax is:

      arp -s <IP address> <MAC address>
      • Replace <IP address> with the IP address you want to "ping".
      • Replace <MAC address> with the corresponding MAC address of the device.
      • Example: arp -s 192.168.1.100 00-AA-BB-CC-DD-EE

  2. Ping the IP Address:

    • Use the ping command with a specific packet size (e.g., 479 bytes). This is achieved with the -l parameter in the ping command.

      ping <IP address> -l 479

      • Replace <IP address> with the same IP address you used in the arp -s command.

      • The -l 479 option specifies the size of the ping payload. The reference includes this payload size.

      • Example: ping 192.168.1.100 -l 479

Important Considerations

  • Administrative Privileges: You need administrator privileges to modify the ARP table.
  • ARP Cache: Adding static ARP entries is generally discouraged in dynamic network environments. They can cause conflicts if the MAC address of the IP address changes. Remember to remove the entry using arp -d <IP address> when finished.
  • Purpose: This method primarily tests basic network connectivity after establishing a mapping between an IP address and MAC address.

Table Summarizing the Commands

Command Description Example
arp -s Adds a static entry to the ARP cache. arp -s 192.168.1.100 00-AA-BB-CC-DD-EE
ping <IP> -l <size> Sends ICMP Echo Request packets of a specified size to a target IP address. ping 192.168.1.100 -l 479
