如何通过域名转ip

[has39]

谁给段代码?

比如输入www.sina.com.cn 可以得到 ip为218.30.66.67

WINDOWS有提供DNS解析命令啊!!!1

#include <windows.h>
#include <winsock.h>
#include <stdio.h>

void main()
{
WSADATA wsaData;
char szHostname[100];
HOSTENT *pHostEnt;
int nAdapter = 0;
struct sockaddr_in sAddr;

if (WSAStartup(0x0101, &wsaData))
{
printf("WSAStartup failed %s\n", WSAGetLastError());
return;
}

pHostEnt = gethostbyname( "www.sina.com.cn");

while ( pHostEnt->h_addr_list[nAdapter] )
{
// pHostEnt->h_addr_list[nAdapter] is the current address in host
// order.

// Copy the address information from the pHostEnt to a sockaddr_in
// structure.
memcpy ( &sAddr.sin_addr.s_addr, pHostEnt->h_addr_list[nAdapter],
pHostEnt->h_length);

// Output the machines IP Address.
printf("Name: %s\nAddress: %s\n", pHostEnt->h_name,
inet_ntoa(sAddr.sin_addr));

nAdapter++;
}
WSACleanup();
return;

}
