Dns.GetHostEntry Method (IPAddress)

The GetHostEntry method queries a DNS server for the IP addresses and aliases associated with an IP address.

Note:
This member emits trace information when you enable network tracing in your application. For more information, see Network Tracing.

The following code example uses the GetHostEntry method to resolve an IP address to an IPHostEntry instance.

public static void DoGetHostEntry(string hostname)
{
    IPHostEntry host;

    host = Dns.GetHostEntry(hostname);

    Console.WriteLine("GetHostEntry({0}) returns:", hostname);

    foreach (IPAddress ip in host.AddressList)
    {
        Console.WriteLine("    {0}", ip);
    }
}

// Determine the Internet Protocol(IP) addresses for my host.
static void DoGetLocalHostAddress()
{
    IPAddress * myHost[] = Dns::GetLocalHostAddresses();

    Console::Write("IPs for my host: ");

    IEnumerator* ips = myHost->GetEnumerator();
    while (ips->MoveNext())
    {
        Console::Write("{0} ", ips->Current);
    }
    Console::WriteLine("");        
}
