https://github.com/knownsec/ksubdomain/blob/master/core/device.go
68行改为：

if dns.QR {
	continue
}
for _, v := range dns.Questions {
	if string(v.Name) == domain {
		ethLayer := packet.Layer(layers.LayerTypeEthernet)
		if ethLayer != nil {
			eth := ethLayer.(*layers.Ethernet)
			signal <- EthTable{SrcIp: data[drviceName].SrcIp, SrcIpV6: data[drviceName].SrcIpV6, Device: drviceName, SrcMac: eth.SrcMAC, DstMac: eth.DstMAC}
			// 网关mac 和 本地mac
			return
		}
	}
}

这样可以保证 net.LookupHost所走的系统dns，发出dns请求后没有收到dns回包也可以获取网卡
