我知道远程机器名，这台机器在同一个网络上。
如果我从命令提示符下 ping 那台机器，我也会得到 IP 信息。

如何在wxWidgets或boost中通过编程实现获取IP地址？
回答:
C 函数:
const wxString GetIPbyName(const wxString& name)
{
struct hostent* pHostInfo;
pHostInfo = gethostbyname(name.c_str());
in_addr * address = (in_addr *)pHostInfo->h_addr;
std::string ip_address = inet_ntoa(*address);
return ip_address;
}
wxWidgets:
wxIPV4address ipv4;
ipv4.Hostname(m_currentServer);
wxString m_currentServer = ipv4.IPAddress();
我不知道上面在多个事件网卡的情况下会如何表现。
