have you changed zone registration?

there is DNS FQDN reference

if you change dns fqdn you have to update zone on your NIC

as it on NIC it or where you registered the domain

Subject: problems changing NS records

Until a few hours ago, I had several domains and 3 nameservers for them:<> (master,<> (slave,<> (slave,

Then I tried to migrate to a new master,<> ( Here is the migration steps I followed:

1) I configured Bind on the new server as master for all domains
2) I added the master IP address to the two slaves with:

masters vbitdnsmasters {;; };

zone "<>" {
        type slave;
        masters { vbitdnsmasters; };
        file "/var/lib/bind/";

and so on for all other zones.

3) I updated the NS records in the zone files, and in the control panel of the domain registrar

Now all the domains have problems. IntoDNS reports:

Nameservers A records    ERROR: Some of your DNS servers do not have A records at all. I could not find any A records for the following DNS servers:<>

You must have A records for all of your nameservers.


dig @<> -t ns<>
dig @<><>
dig @<><>
dig @<> -t mx<>

all work as expected. Meanwhile, the same queries against sometime work, sometime reply SERVFAIL.

I don't know what I did wrong. Please help.
