例如，本機的MAC地址為: 00-1C-47-CE-FE-02，在發送數據包的時候，如何將其修改為00-11-42-DF-EE-01
1.不能采用修改網卡的MAC地址的方式，因為修改後的地址是隨機動態的，要像方法中的一個參數一樣，隨時修改，不會影響網絡狀態，不會閃斷
2.修改發送數據包的MAC地址後，要能夠接收到返回的數據包
小弟不大懂網絡方面的知識，但無奈領導布置了任務，
不知能否實現，能實現，麻煩說明具體實現方法，如不能實現，也麻煩具體說明一下不能實現的理由。
如有興趣的大神可以加我QQ392124082研究研究
小弟感激不盡
物理MAC 地址是不能在系統或者程序中修改的，但對方通信端是 web服務器或者電信服務器，修改系統注冊表就可以了，能達到模擬真實MAC達到欺騙的目的，本人實測是完全可行的，但同一網域相同的MAC 會沖突，會導致一方不能聯網，如果路由端經過ARP雙向綁定你是沒有任何辦法的，這種概率非常低，下面是一個C#實例（非本人所寫，但實測可行），可以隨機修改也可以改成 指定MAC，主要還是看你要實現什麼目的，請詳細說明。
