网络地址顺序的问题？

Question

网络地址顺序的问题？我用SPI拦截了IP数据包(拦截Connect SendTo)，但我发现取得的IP地址有时候是反的！？
用FTP对 killpw.51.net 测试时，在ini文件中是 249.3.157.211 //反的
用IE测试时，在ini文件中是 192.168.0.188  //正确
在DLL中的部分代码int WSPAPI WSPConnect(
  SOCKET s,
  const struct sockaddr FAR * name,
  int namelen,
  LPWSABUF lpCallerData,
  LPWSABUF lpCalleeData,
  LPQOS lpSQOS,
  LPQOS lpGQOS,
  LPINT lpErrno
  )
{ if(s!=m_socketTemp && s!=INVALID_SOCKET)
{

SOCKADDR_IN *pInetAddr = (SOCKADDR_IN*)name;
DWORD *pRemoteIp = (DWORD*)&pInetAddr->sin_addr; wsprintf(m_cTemp,"%s",commonfunction.DIPToSIP(pRemoteIp));
m_socketTemp=s;
WritePrivateProfileString("d","d",m_cTemp,"1.ini");
EnterCriticalSection(&m_csIPMoniter);
q.push(m_cTemp);
LeaveCriticalSection(&m_csIPMoniter); } return NextProcTable.lpWSPConnect(s, name, namelen, lpCallerData, lpCalleeData, lpSQOS, lpGQOS, lpErrno);
}
int WSPAPI WSPSendTo(
 SOCKET s,
 LPWSABUF lpBuffers,
 DWORD dwBufferCount,
 LPDWORD lpNumberOfBytesSent,
 DWORD dwFlags,
 const struct sockaddr FAR * lpTo,
 int iTolen,
 LPWSAOVERLAPPED lpOverlapped,
 LPWSAOVERLAPPED_COMPLETION_ROUTINE lpCompletionRoutine,
 LPWSATHREADID lpThreadId,
 LPINT lpErrno
 )
{ if(s!=m_socketTemp && s!=INVALID_SOCKET)
{ SOCKADDR_IN *pAddr = (SOCKADDR_IN*)lpTo;
DWORD *pRemoteIp = (DWORD*)&pAddr->sin_addr;
wsprintf(m_cTemp,"%s",commonfunction.DIPToSIP(pRemoteIp));
m_socketTemp=s;
WritePrivateProfileString("d","d",m_cTemp,"1.ini");
EnterCriticalSection(&m_csIPMoniter);
q.push(m_cTemp);
LeaveCriticalSection(&m_csIPMoniter); } return NextProcTable.lpWSPSendTo(s, lpBuffers, dwBufferCount, lpNumberOfBytesSent, dwFlags, lpTo
, iTolen, lpOverlapped, lpCompletionRoutine, lpThreadId, lpErrno);

}

Answer 1

字节顺序转化的四个函数：
htons();ntohs(); //将主机顺序转换为网络顺序，其中s表示short
htonl();ntohl(); //将网络顺序转换为主机顺序，其中l表示long

Answer 2

不行呀,我把4个函数都试了,还是不行.
当我用 htonl 时候,可以IE上网,但不能登陆传奇网络游戏!!代码如下;
if(s!=m_socketTemp && s!=INVALID_SOCKET)
{
  SOCKADDR_IN *pAddr   = (SOCKADDR_IN*)lpTo;
  DWORD *pRemoteIp= (DWORD*)&pAddr->sin_addr;   *pRemoteIp= (DWORD)ntohl(*pRemoteIp)//我是本地拦截Connect SendTo,在此之前,已经
                                      //转换成网络格式,现在转换回来  wsprintf(m_cTemp,"%s",commonfunction.DIPToSIP(pRemoteIp));
  m_socketTemp=s;
  WritePrivateProfileString("d","d",m_cTemp,"1.ini");
  EnterCriticalSection(&m_csIPMoniter);
  q.push(m_cTemp);
  LeaveCriticalSection(&m_csIPMoniter);
}
