>                 URL: https://issues.apache.org/jira/browse/CASSANDRA-4359
>             Project: Cassandra
>          Issue Type: Bug
>          Components: Core
>    Affects Versions: 1.1.1
>         Environment: Windows 7
>            Reporter: Gerben Kegel
>            Priority: Minor
>   Original Estimate: 2h
>  Remaining Estimate: 2h

> You can not use IPv6 under Windows 7 because nio is not supported. You receive an error: "Address family not supported by protocol family".
> Yuu can reproduce it by changing the rpc_address to "[::1]" and start Cassandra under Windows 7
> A workaround is to disable nio while using IPv6 under Windows 7. (Other windows versions might also be affected.) Example:
> {code:title=MessagingService.java}
> ServerSocket socket;
> if (nioSupported(localEp)) {
>   serverChannel = ServerSocketChannel.open();
>   socket = serverChannel.socket();
> } else {
>   socket = new ServerSocket();
> }
> private boolean nioSupported(InetAddress localEp) {
>   String os = System.getProperty("os.name");
>   return !(localEp instanceof Inet6Address && os.equals("Windows 7"));
> }
> {code}
