Issue Slave DNS Manager

[christanto]

Server operating system version

Ubuntu 22.04

Plesk version and microupdate number

Version 18.0.62 Update #2

Hello,

I'm trying to use Slave DNS Manager. Both my primary and slave servers are configured. When I perform a resync, I can see the log on the slave server.

In Plesk, I have set the A records as follows:


However, when I run the following commands:
dig @193.30.121.199 ns1.it-mation.de A
dig @193.30.121.199 ns2.it-mation.de A

I get this result:

root@ubuntu:~# dig @193.30.121.199 ns1.it-mation.de A
dig @193.30.121.199 ns2.it-mation.de A

I've tried resyncing several times, but the IP addresses for NS1 and NS2 remain unchanged. Due to DENIC regulations, I need to have a minimum of two different IPv4 addresses to use my own nameserver.

Is there a solution for this?

Any help would be greatly appreciated.

Cheers
Ade

Hi!

Based on the commands' output, you tried to ask Plesk (primary nameserver) and got the same IP-address for ns1 and ns2. In other words, the issue is somewhere in the settings on the primary nameserver (not in the secondary nameserver or in Slave DNS Manager's settings).

Need to figure out what needs to change on the primary nameserver to get different IP-addresses for ns1 and ns2.
The first thing I can suggest is checking warnings on the DNS setting page for the domain, probably need to apply the changes,


And to be honest, I can't imagine what else makes sense to check...
