Declare DNS servers in my domain register provider

I have 2 dns servers in the same static ip.

hostname - dns1.domain.com
hostname - dns2.domain.com

What do i have to put in the control panel of my domain register provider ?

A records pointed to dns1 and dns2?

Best regards

 

you can not run 2 public dns on the same ip

 

Thanks for the clarification.

Then I will use two IPs. In differents locations.

dns1.domain.com - 80.58.60.150
dns2.domain.com - 80.58.65.130

Then in my domain provider control panel do I have to add two A records? dns1 pointer to 80.58.60.150 and dns2 pointer to 80.58.65.130?

And change provider dns for dns1.domain.com and dns2.domain.com ?

Best regards

 

I was referring to the public IP, which I use for each server (Mail, Web, Db ...) But in the local network each host has a unique IP. Did you mean local IP or public IP?

 

Why not? I do the same. Denic won't allow it for .de TLDs but you can do it for other TLDs.

Hi,
I tested the dns of sjau in my domain (GoDaddy) and can be added. Check if the names are different but not if the ip is different.

I added an A record dns1 pointing to my public ip. It looks like this. I will add the second and try to change the domain dns to see if it works.

 

Hello!

Public IP: 150.200.2.56
Local IP's:
gateway: 192.168.1.1
web1.example.com - 192.168.1.50
dns1.example.com - 192.168.1.51
dns2.example.com - 192.168.1.52


DNS-Zone:
Server: dns1.example.com
Client: clientC1
Zone(SOA): example.com.
NS: dns1.example.com
E-mail: [email protected]
Refresh: 7200 seconds
Retry: 540 seconds
Expire: 604800 seconds
Minimum: 3600 seconds
TTL: 3600 seconds

Records:
A example.com. 150.200.2.56
A mail 150.200.2.56
A www 150.200.2.56
MX example.com. mail.example.com
NS example.com. dns2.example.com
NS example.com. dns1.example.com
TXT example.com. v=spf1 mx a ~all

WEB1.example.com (ispconfig3 master server)
DNS1.example.com
DNS2.example.com

On the router I have open port 53 to dns1.example.com (192.168.1.51) but I do not know which port to open for dns2.example.com (192.168.1.52) because the router does not allow me to open the same port for more than one ip address. Is it possible to use another port? For example the 54?

In System --> Server Services
web1.example.com --> Web/Yes - File/Yes the rest No.
dns1.example.com --> DNS/Yes - the rest No.
dns2.example.com --> DNS/Yes - the rest No. :: Is mirror of Server: dns1.example.com

Can you tell me what I'm doing wrong?

Best regards

 

Thank you!

I changed dns2.example.com another public IP (150.200.2.57). In the master database added to the root user with privileges for the public ip 150.200.2.57.

In the firewall of dns2.example.com (ufw) I opened the ports udp/tcp 53 and tcp 3306, on the router of dns2.example.com I opened ports udp/tcp 53 and tcp 3306.

In ISPConfig 3 --> System --> Server Config --> dns2.example.com I changed the IP address 192.168.1.52 to 150.200.2.57

In Domain register I changed A record dns2 150.200.2.56 to dns2 150.200.2.57

Then,
