DNSReport indique des failles

[philippe69]

Bonjour, lorsque je fais un dnsreport sur mon site web, le rapport m'indique des failles de sécurité. Je ne sais pas résoudre ces problèmes. Quelqu'un a-t-il une idée ?

Pour info, j'ai un serveur dédié chez ovh.

Merci d'avance de votre aide

Voilà les points rouges de mon report :

--------------------- point 1 -----------------------------

FAIL Lame nameservers ERROR: You have one or more lame nameservers. These are nameservers that do NOT answer authoritatively for your domain. This is bad; for example, these nameservers may never get updated. The following nameservers are lame:

212.27.32.132

--------------------- point 2 -----------------------------

FAIL Stealth NS record leakage Your DNS servers leak stealth information in non-NS requests:

Stealth nameservers are leaked [i.gtld-servers.net.]!

Stealth nameservers are leaked [j.gtld-servers.net.]!

Stealth nameservers are leaked [k.gtld-servers.net.]!

Stealth nameservers are leaked [l.gtld-servers.net.]!

Stealth nameservers are leaked [m.gtld-servers.net.]!

Stealth nameservers are leaked [a.gtld-servers.net.]!

Stealth nameservers are leaked [b.gtld-servers.net.]!

Stealth nameservers are leaked [c.gtld-servers.net.]!

Stealth nameservers are leaked [d.gtld-servers.net.]!

Stealth nameservers are leaked [e.gtld-servers.net.]!

Stealth nameservers are leaked [f.gtld-servers.net.]!

Stealth nameservers are leaked [g.gtld-servers.net.]!

Stealth nameservers are leaked [h.gtld-servers.net.]!

This can cause some serious problems (especially if there is a TTL discrepancy). If you must have stealth NS records (NS records listed at the authoritative DNS servers, but not the parent DNS servers), you should make sure that your DNS server does not leak the stealth NS records in response to other queries.
