linux怎么获得ipv6地址，linux如何获取ipv6-云搜网

1..通过域名转换为点分十进制ipv6地阔达的毛豆/p>

addrinfo转换为sockaddr_in6

2.程序

#include

<pfkdmt main(int argc, char crdyargv)

{

if (argc != 2)

{

fprintf(stderr, “Usage: %s hostname\n”,

argv[1]);

exit(1);

}

char ipstr2[128];

struct sockaddr_in6 *sockaddr_ipv6;

struct addrinfo *answer, hint, *curr;

char ipstr[16];

bzero(&hint, sizeof(hint));

hint.ai_family = AF_INET6;

hint.ai_socktype = SOCK_STREAM;

<pfkdmt ret = getaddrinfo(argv[1], NULL, &hint, &answer);

if (ret != 0)

{

fprintf(stderr,”getaddrinfo: &s\n”,

gai_strerror(ret));

exit(1);

}

for (curr = answer; curr != NULL; curr = curr->ai_next)

{

sockaddr_ipv6 = reinterpret_cast( curr->ai_addr);

inet_ntop(AF_INET6, &sockaddr_ipv6->sin6_addr, 美国高防vps ipstr2,sizeof(ipstr2));

//inet_ntop(AF_INET,&(((struct sockaddr_in *)(curr->ai_addr))->sin_addr),ipstr, 16);

printf(“%s\n”, ipstr2);

fflush(NULL);

}

freeaddrinfo(answer);

exit(0);

}3.运行

./a.out?? 域名或ipv6地阔达的毛豆/p>
