我遇到一個有趣的現象:
Jan 11 06:42:48 servername kernel: arp: 123.123.123.123 moved from aa:bb:cc:53:c2:df to aa:bb:cc:53:c2:dd on de0
Jan 11 06:42:48 servername kernel: arp: 123.123.123.123 moved from aa:bb:cc:53:c2:dd to aa:bb:cc:53:c2:df on de0
我的機器在 123.123.123./24 下,以上訊息一天至少出現一次,有時會出現二、三
十次。這台機器是同網域網管管理的機器,跑 WinNT。該網管表示因為涉及資安議
題,不願說明這麼做的原因。
有人知道機常變換 MAC 會有什麼好處或壞處嗎?
