DNS General - Change the default suffix used for DNS name of additional nic


The SovLabs DNS module uses a default suffix for the DNS name of an additional network interface (nic) by default.

You can override that default suffix using the custom property, SovLabs_AdditionalNicOverrideHostname-nic# where # is a value 1-9

  • For example, if you have a nic1 on the server myserver.mydomain.com, the default behavior of the DNS module is to append "-nic1" to the base-name and use that for the DNS entry for that network interface. 
    • The resulting name would be myserver-nic1.mydomain.com
      • To override "nic1" with your own custom string, set SovLabs_AdditionalNicOverrideHostname-nic1 to a value of your string, for example "-nfs".
        • The resulting DNS name for nic1 would be myserver-nfs.mydomain.com

If you want a dash in the nic suffix, you must include it in the string value for the SovLabs_AdditionalNicOverrideHostname-nic# property.  


Affected Versions

  • This property was implemented in SovLabs version 2018.2.4


  • The property SovLabs_AdditionalNicOverrideHostname-nic# does NOT perform any validation checks against the set DNS configuration to determine if the hostname already exists.
    • Please be sure that the name selected is not already in use or the provision may fail.
  • The property SovLabs_AdditionalNicOverrideHostname-nic# can be created as Custom Property in the Administration tab (Administration>Property Dictionary>Property Definitions) and selected via the dropdown inside the blueprint for ease-of-use
