Examples
The following example uses the AddressList property to access the IP addresses that are associated with the IPHostEntry.
void GetIpAddressList( String^ hostString )
{
try
{
// Get 'IPHostEntry' object containing information
// like host name, IP addresses, aliases for a host.
IPHostEntry^ hostInfo = Dns::GetHostByName( hostString );
Console::WriteLine( "Host name : {0}", hostInfo->HostName );
Console::WriteLine( "IP address List : " );
for ( int index = 0; index < hostInfo->AddressList->Length; index++ )
Console::WriteLine( hostInfo->AddressList[ index ] );
}
catch ( SocketException^ e )
{
Console::WriteLine( "SocketException caught!!!" );
Console::WriteLine( "Source : {0}", e->Source );
Console::WriteLine( "Message : {0}", e->Message );
}
catch ( ArgumentNullException^ e )
{
Console::WriteLine( "ArgumentNullException caught!!!" );
Console::WriteLine( "Source : {0}", e->Source );
Console::WriteLine( "Message : {0}", e->Message );
}
catch ( Exception^ e )
{
Console::WriteLine( "Exception caught!!!" );
Console::WriteLine( "Source : {0}", e->Source );
Console::WriteLine( "Message : {0}", e->Message );
}
}
public void GetIpAddressList(String hostString)
{
try
{
// Get 'IPHostEntry' object containing information like host name, IP addresses, aliases for a host.
IPHostEntry hostInfo = Dns.GetHostByName(hostString);
Console.WriteLine("Host name : " + hostInfo.HostName);
Console.WriteLine("IP address List : ");
for(int index=0; index < hostInfo.AddressList.Length; index++)
{
Console.WriteLine(hostInfo.AddressList[index]);
}
}

Console.WriteLine("Message : " + e.Message);
}
}
