Your local nameservers don't return IP addresses

[Oualid]

Hi,
i have this error if i check all my website with viewdns.info :

Oops! Your local nameservers don't return IP addresses (glue) along with your NS records! This isn't a fatal error but means an extra lookup needs to be performed increasing the load time to your site. You can fix this by adding A records for each of the nameservers listed above.

and

Oops! The following nameservers listed at the parent servers didn't respond to DNS requests:
ns2.myhostdomain.com.
ns1.myhostdomain.com.
This means that some people won't be able to view your site! It also means some of the tests below which check for the same results across all your local nameservers will fail.

My website work fine but i want to resolve this problem ! Who to do ?
"/usr/sbin/iptables -n -L" gives :

Hello,

You can manually edit the /etc/resolv.conf file on your system if you want to change your DNS resolvers. Make sure you are using the resolvers recommended by your hosting provider or data center.

Thank you.

in /etc/resolv.conf i have a good ip ns1 and ns2 :

search ovh.net
nameserver 158.xxx.xxx.xxx
nameserver 8.xx.xxx.xxx

Hello,

Check with your hosting provider to see if either of those resolvers were down at the time you received the resolver failure notification.

Thank you.
