使用boost asio枚举我的卡的ipv4和ipv6地址 [英] enumerating ipv4 and ipv6 address of my cards using boost asio

问题描述

我试图枚举我的PC上所有网卡(我有2张卡)的ipv4和ipv6地址.

I am trying to enumerate ipv4 and ipv6 addresses of all the network cards(I have 2 cards) my pc.

我正在使用以下代码来做到这一点.

I am using the following code to do that.

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;

    }

该代码显示正确的ipv4地址，但不显示ipv6.这是输出

The code displays correct ipv4 addresses but not ipv6. Here is the output

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

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

I have very minimum knowledge of ipv6. When I list the information about network interface using ipconfig/all I see that the actual ipv6 addresses are

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.

Can someone please guide me how to list the ipv6 addresses. Thanks.

推荐答案

如果平台是Windows 7 SP1，则链接本地接口将被跳过，因为Windows将其标记为" SkipAsSource " getaddrinfo 不会返回它们，因此都不会增强.

If the platform is Windows 7 SP1 the link-local interfaces are being skipped as they are tagged "SkipAsSource" by Windows which means that getaddrinfo will not return them and hence neither will Boost.

您可以尝试使用以下命令检查标志:

You can try to inspect the flag with the following command:

netsh int ipv6 show addresses level=verbose

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