Nameservers A recordsERROR: Some of your DNS servers do not have A

servers:

You must have A records for all of your nameservers.


this says it precisely: ns2.virtualbit.it does not exist.


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


I have no idea where did you get the information that it has IP
136.243.232.143, the IP mey answer, but it is not ns2.virtualbit.it because
ns2.virtualbit.it simply does not exist.

note that domain virtualbit.it is registered to sulweb.org nameservers,
which already makes it inapt for using NS record and it also has problems:

"

ns2.sulweb.org

"


...not mentioning that sulweb.org itself is hosted by seflow.net which makes
it inapt too...

find better nameservers for your domain.

Oh dear, this is a bit of a rabbit hole.

I can't resolve any of those names you listed, so let's try to find out
why...

$ dig +noall +authority ns virtualbit.it @dns.nic.it.
virtualbit.it.  10800   IN  NS  names.sulweb.org.
virtualbit.it.  10800   IN  NS  ns2.sulweb.org.
virtualbit.it.  10800   IN  NS  ns11.sulweb.org.

$ dig +noall +authority ns sulweb.org. @a0.org.afilias-nst.info.
sulweb.org. 86400   IN  NS  dns2.seflow.net.
sulweb.org. 86400   IN  NS  dns3.seflow.net.
sulweb.org. 86400   IN  NS  dns1.seflow.net.

$ dig +noall +answer dns1.seflow.net. dns2.seflow.net. dns3.seflow.net.
dns1.seflow.net.14314   IN  A   94.198.98.168
dns2.seflow.net.14330   IN  A   193.70.56.6
dns3.seflow.net.14365   IN  A   144.217.99.49

$ dig +short dns1.seflow.net. dns2.seflow.net. dns3.seflow.net. |
  while read a; do dig ns sulweb.org @$a; done | grep status:
;; ->>HEADER<<- opcode: QUERY, status: REFUSED, id: 14143
;; ->>HEADER<<- opcode: QUERY, status: REFUSED, id: 41727
;; ->>HEADER<<- opcode: QUERY, status: REFUSED, id: 19805

OK, so seflow.net is no longer hosting sulweb.org, which means domains
like virtualbit.it that depend on sulweb.org are offline.

Tony.

Re: problems changing NS records

2018-04-26 Thread Alberto Colosi 
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:

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 recordsERROR: 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.
