SEO优化建议：

• **标题和描述：**使用简洁明了的语言描述代码的功能，并包含相关关键词，例如“Python”、“Scapy”、“网络安全”、“ARP欺骗”等。
• **关键词：**列出与代码相关的关键词，方便搜索引擎收录。
• **代码注释：**为代码添加清晰易懂的注释，解释代码的功能和实现方式。
• **代码格式：**使用规范的代码格式，提高代码的可读性。
• **文章结构：**使用清晰的标题和段落结构，使文章更易于阅读和理解。
• **相关链接：**添加指向相关资源的链接，例如Scapy官方文档、网络安全教程等。

更改后的代码说明：

• 将所有中文双引号改为英文单引号。
• 添加了代码注释，解释代码的功能和实现方式。
• 对代码进行了格式化，提高代码的可读性。
• 添加了SEO优化建议，方便搜索引擎收录。
