arp命令获得的mac地址错误

[xhsh]

我运行arp命令获得的信息如下：

为什么会有那么多机器的mac地址识别错误，都是c4:ca:d9:35:06:08？

这个似乎是网关的mac地址，如果这些机器不是连在同一个交换机下，如何得到那些机器的真实的mac地址？

arp with no mode specifier will print the current content of the table.
It is possible to limit the number of entries printed, by specifying an hardware address type, interface name or host address.

Many thanks. But could you answer the second question, namely, how to get the real MAC address of the computer that is not in the same local network?

Local Network 通常透過 IP 分享器 或 路由器 連線
你有登入 IP 分享器 或 路由器 的帳號及密碼嗎 ?
登入 登入 IP 分享器 或 路由器 檢查 MAC 比較簡單

如果沒有 登入 IP 分享器 或 路由器的帳號及密碼
最好向網管人員尋求幫助
