Until a few hours ago, I had several domains and 3 nameservers for them:
ns1.virtualbit.it (master, 136.243.232.142)
ns11.virtualbit.it (slave, 158.69.210.19)
ns2.virtualbit.it (slave, 136.243.232.143)
Then I tried to migrate to a new master, names.virtualbit.it (46.4.38.130).
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 { 136.243.232.142; 46.4.38.130; };
zone "acquaritalia.it" {
type slave;
masters { vbitdnsmasters; };
file "/var/lib/bind/acquaritalia.it.db";
};
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:
ns2.virtualbit.it
You must have A records for all of your nameservers.
"
However:
dig @136.243.232.143 -t ns acquaritalia.it
dig @136.243.232.143 acquaritalia.it
dig @136.243.232.143 www.acquaritalia.it
dig @136.243.232.143 -t mx acquaritalia.it
all work as expected. Meanwhile, the same queries against 8.8.8.8 sometime
work, sometime reply SERVFAIL.
I don't know what I did wrong. Please help.
