网络编程部分源码->校验和、隐藏IP方法、取得本地MAC********************************
//注意!!!!!!
//IP的检查和只是IP头部的20个字节，不然过不了网关!!!!
//而TCP和UDP和检查和是数据和头部都包括!!
//在计算检查和之前IP或UDP或TCP报头中 所有的成员 必须被初始化，包括 checksum!!!
//为了保证系统和机器的******兼容性******，在定义网络结构体或共用体时要加上
#pragma pack(1)
#pragma pack()
//如：
#pragma pack(1)
typedef struct response
{
unsigned short name;
unsigned short type;
unsigned short classes;
unsigned int ttl;
unsigned short length;
unsigned int addr;
}RESPONSE,*PRESPONSE;
#pragma pack()
//sizeof(RESPONSE)==16，如果不加#pragma pack那么sizeof(RESPONSE)==20
//局域网内相同网段下的IP地址，数据包直接发给该主机的MAC地址，不同网段下的，数据包发给网关，
//如：202.198.153.17->202.198.153.64 以太包目的地址为202.198.153.64 的MAC地址
//如：202.198.153.17->202.198.159.139 以太包目的地址为202.198.153.254(网关) 的MAC地址
