You will get all the addresses using getAllByName(), and you need to use the one that is IPV6. If your client is an IPV6 client, that will be just fine. You probably need to enforce IPV6 on the client too : System.setProperty( " |java.net.preferIPv6Addresses", "true" ); The real issue here is when you don't know if your client is IPV4 or IPV6. OTOH, if the client is IPV4 only and the server is IPV6 only, you are doomed. ||wdyt ?|
