常用示例
Ping a host using ARP
sudo arping [192.168.1.1]
Ping using a specific interface
sudo arping -I [eth0] [192.168.1.1]
Send a specific number of requests
sudo arping -c [5] [192.168.1.1]
Detect duplicate IP addresses on the network
sudo arping -D [192.168.1.1]
Quit after first reply
sudo arping -f [192.168.1.1]
说明
arping sends ARP requests to a target host and displays responses. Unlike ICMP ping, ARP operates at layer 2 and cannot be blocked by IP firewalls. The tool is useful for verifying layer 2 connectivity, finding MAC addresses, and detecting duplicate IP addresses on a network.
