Name servers configuration

Name servers configuration

 


ISPmanager is used as a master name server. You can use DNSmanager as slave name servers. There are several ways to set up name servers using ISPmanager. 

  1. ISPmanager + 2 DNSmanager.
  2. ISPmanager + DNSmanager.
  3. ISPmanager.

Comparison of the configuration schemes: 

Software productsProsCons
ISPmanager + 2 DNSmanagerBetter security of the DNS system and ensure that your domain names are always accessible.The risk that two servers in different parts of the globe are not accessible at the same time is considerably low.You must have two additional servers that should locate on different physical servers that are located in different places. Due to failures, the information will update only on one slave server. If the information differs on both slave servers, sites won't work properly.
ISPmanager + DNSmanagerYou do not need to use several slave servers.You must have a powerful master server that will be able to process both requests and name servers. In case of a high load on master servers, sites may open more slowly, as DNS requests will be processed for a longer time. The first scenario is more fault-tolerant.
ISPmanagerYou do not need to use several slave servers.The service responsible for DNS may fail. In this case, all the main services will continue running, but users won't be able to access them as their domains do not work.You must have a powerful master server that will be able to process requests and name servers. in case of a high load on master servers, sites may open more slowly, as DNS requests will be processed for a long time.

ISPmanager + 2 DNSmanager

Perform the following steps to configure the name servers:

  1. Connect the servers with DNSmanager. For more information please refer to the article Integration with DNSmanager.
  2.  Make sure that the names servers respond from the IP addresses to which they are assigned: 
    1. Navigate to ISPmanager → Domain → Domain names → Add and create a domain, e.g. "domain.com". For more information please refer to the article How to create a domain name.
    2. Navigate to ISPmanager → Domain → Domain names → Manage DNS records and check the NS-records of the domain. Check that the IP addresses of both DNSmanager are specified in the Value field for the NS-records.  For more information please refer to the article Resource records.
    3. Update the data on the slave servers: ISPmanager → Domain names → Update on NS.
    4. Execute the following command to check the information about the name servers: 
dig domain.com @<IP address of the slave DNS>

The response should look like this:

; <<>> DiG 9.8.1-P1 <<>> domain.com @<IP address of the slave DNS>
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 46010
;; flags: qr aa rd; QUERY: 1, ANSWER: 1, AUTHORITY: 2, ADDITIONAL: 2
;; WARNING: recursion requested but not available

;; QUESTION SECTION:
;domain.com.                    IN      A

;; ANSWER SECTION:
domain.com.             3600    IN      A       <ISPmanager IP address>

;; AUTHORITY SECTION:
domain.com.             3600    IN      NS      ns2.domain.com.
domain.com.             3600    IN      NS      ns1.domain.com.

;; ADDITIONAL SECTION:
ns1.domain.com.         3600    IN      A       <ISPmanager IP address>
ns2.domain.com.         3600    IN      A       <DNSmanager IP address>

3. Specify the name servers with the IP address on the domain registrar side:

ns1.domain.com/<DNSmanager 1 IP address>
ns2.domain.com/<DNSmanager 2 IP address>

Delegating the domain to the name server can take up to 24-48 hours. Once completed, you can use them for registration and delegation of new domain names.

ISPmanager + DNSmanager

Perform the following steps to configure the name servers:

  1. Connect the servers with DNSmanager. For more information please refer to the article Integration with DNSmanager.
  2.  Make sure that the names servers respond from the IP addresses to which they are assigned: 
    1. Navigate to ISPmanager → Domain → Domain names → Add and create a domain, e.g. "domain.com". For more information please refer to the article How to add a domain name.
    2. Navigate to ISPmanager → Domain → Domain names → Manage DNS records and check the NS-records of the domain. Check that the primary and additional IP addresses of ISPmanager are specified in the Value field for the NS-records.  For more information please refer to the article Resource records.
    3. Update the data on DNSmanager: ISPmanager → Domain names → Update on NS.
    4. Execute the following command to check the information about the name servers: 


dig domain.com @<IP address of the slave DNS>

The response should look like this:

; <<>> DiG 9.8.1-P1 <<>> domain.com @<IP address of the slave DNS>

ISPmanager 

Perform the following steps to configure the name servers:

  1. The server with ISPmanager must have at least 2 IP addresses.
  2.  Make sure that the names servers are received from the IP addresses on which they are located: 
    1. Navigate to ISPmanager → Domain → Domain names → Add and create a domain, e.g. "domain.com". For more information please refer to the article How to create a domain name.
    2. Navigate to ISPmanager → Domain → Domain names → Manage DNS records and check the NS-records of the domain. Check that domain names corresponded to the IP addresses of both ISPmanager are specified in the Value field for the NS-records.  For more information please refer to the article Resource records.
    3. Execute the following command to check the information about the name servers:


dig domain.com @<ISPmanager IP address>

The response should look like this:

; <<>> DiG 9.8.1-P1 <<>> domain.com @<ISPmanager IP address>

ns2.domain.com.         3600    IN      A       <ISPmanager primary IP address>

3. Specify the name server with the IP address on the domain registrar side:

ns1.domain.com/<ISPmanager additional IP address>
