C语言网络编程，如何更改自己编的程序的本地ip？

我的ip地址只能在内部使用

#include <stdio.h>
#include <stdlib.h>
#include <sys/types.h>
#include <winsock2.h>
main()
{
    WSADATA wsaData;
    int err=WSAStartup(MAKEWORD(2,2),&wsaData);
    SOCKET sock=socket(AF_INET,SOCK_STREAM,0);//*初始化
    struct sockaddr_in serv_addr2;
    serv_addr2.sin_family=2;//*IPv4地址
    serv_addr2.sin_addr.s_addr=inet_addr("192.168.2.2");//*ip
    serv_addr2.sin_port=htons(2305);//*端口号
    bind(sock,(struct sockaddr*)&serv_addr2,sizeof(serv_addr2));
    int f=listen(sock,200);//*监听
    int len=sizeof(struct sockaddr_in);
    SOCKADDR clntaddr;
    SOCKET data;
    data=accept(sock,&clntaddr,&len);//*接收请求
    char *data2;
    data2=(char*)malloc(sizeof(char)*1024*1024);
    unsigned long long int length=0;
    while(length<1024*1024)
    {
        data2[length]='a';
        length++;
    }
    data2[length]='\0';
    int j;
    send(data,data2,1024*1024,0);//*发送信息
    closesocket(sock);
    closesocket(data);
    free(data2);
    //*关闭套接字 
    WSACleanup();
    system("pause");
    return 0;
}

#include <stdio.h>
#include <stdlib.h>
#include <sys/types.h>
#include <winsock2.h>
main()
{
    char ip[30];
    WSADATA wsaData;
    int err=WSAStartup(MAKEWORD(1,0),&wsaData);
    SOCKET sock=socket(AF_INET,SOCK_STREAM,0);//*初始化
    struct sockaddr_in serv_addr;
    serv_addr.sin_family=AF_INET;//*IPv4地址 
    serv_addr.sin_addr.s_addr=inet_addr("192.168.2.2");//*ip
    serv_addr.sin_port=htons(2305);//*端口号
    connect(sock,(SOCKADDR*)&serv_addr,sizeof(serv_addr));
    system("pause");
//   listen(sock,200);
    char *data;
    data=(char*)malloc(sizeof(char)*1024*1024);
    data[1024*1024]='\0';
    int j;
    recv(sock,data,1024*1024,0);
    printf("%s",data);
    free(data);
    closesocket(sock);//*关闭套接字 
    WSACleanup();
    system("pause");
    return 0;
}
