Hello, I have a domain called xzone.fr and I would add an entry that is www.sub Could you tell me if these line is right in the RFC (because it is running but I don't know if it is running for all) www.sub IN A x.x.x.x So, could I use this syntax or I must create a sub domain sub.xzone.fr and then add www in the sub.xzone.fr file. Thanks, Alexis Albinet
