下面是使用gopacket库实现该功能的示例代码：
”`go package main
import (
"fmt"
"log"
"net"
"time"
"github.com/google/gopacket"
"github.com/google/gopacket/layers"
)
func sendARPRequest(destIP net.IP) {
iface, err := net.InterfaceByName("eth0") // 替换成你的网络接口名称
if err != nil {
log.Fatal(err)
}
srcIP := net.ParseIP("192.168.1.100") // 替换成你的源IP地址
arpLayer := &layers.ARP{
AddrType: layers.LinkTypeEthernet,
Protocol: layers.EthernetTypeIPv4,
HwAddressSize: 6,
ProtAddressSize: 4,
SrcHwAddress: iface.HardwareAddr,
SrcProtAddress: srcIP.To4(),
DstHwAddress: []byte{0, 0, 0, 0, 0, 0},
DstProtAddress: destIP.To4(),
