使用boost asio枚举我的卡的ipv4和ipv6地址

Question

我试图枚举所有网卡的ipv4和ipv6地址(我有2张卡)我的电脑.

我使用以下代码来做到这一点.

using boost::asio::ip::tcp;
boost::asio::io_service io_service;

    tcp::resolver resolver(io_service);
    tcp::resolver::query query(boost::asio::ip::host_name(),"");
    tcp::resolver::iterator it=resolver.resolve(query);

    while(it!=tcp::resolver::iterator())
    {
        boost::asio::ip::address addr=(it++)->endpoint().address();
        if(addr.is_v6())
        {
            std::cout<<"ipv6 address: ";
        }
        else
            std::cout<<"ipv4 address: ";

        std::cout<<addr.to_string()<<std::endl;

    }

代码显示正确的ipv4地址,但不显示ipv6.这是输出

ipv6 address: ::1
ipv4 address: 192.168.10.200
ipv4 address: 192.168.10.236

我对ipv6知之甚少.当我使用ipconfig/all列出有关网络接口的信息时,我看到实际的ipv6地址是

fe80::226:5aff:fe14:5687%5 
fe80::225:64ff:feb2:4f61%4

有人可以指导我如何列出ipv6地址.谢谢.

如果平台是Windows 7 SP1,则跳过链接本地接口,因为它们被Windows 标记为" SkipAsSource ",这意味着它们getaddrinfo不会返回它们,因此也不会提升.

您可以尝试使用以下命令检查标志:

netsh int ipv6 show addresses level=verbose

Address fe80::e0:0:0:0%14 Parameters
