    voici le problème signalé par ma boulangère:

    FAIL
    Open DNS servers
    ERROR: One or more of your nameservers reports that it is an open DNS server. This usually means that anyone in the world can query it for domains it is not authoritative for (it is possible that the DNS server advertises that it does recursive lookups when it does not, but that shouldn't happen). This can cause an excessive load on your DNS server. Also, it is strongly discouraged to have a DNS server be both authoritative for your domain and be recursive (even if it is not open), due to the potential for cache poisoning (with no recursion, there is no cache, and it is impossible to poison it). Also, the bad guys could use your DNS server as part of an attack, by forging their IP address. Problem record(s) are:

    Server 129.142.7.99 reports that it will do recursive lookups. [test]


    See this page for info on closing open DNS servers.


    Je ne pense pas que ce soit un problème temporaire, ça a plutôt l'air d'être lié à la sécurité... Donc... Est-ce grave docteur ? Pourrait on m'expliquer quel est le problème un peu plus précisément ?
