Constellix only offers Secondary DNS through API integrations with Google Cloud DNS, Microsoft Azure, and Amazon Route 53.
If you require Secondary DNS with another provider, or a Master/Slave configuration, we recommend using our other product DNS Made Easy.
How to Configure
- Setup API integration and import zone files
- Update NS records for both providers
- Update nameservers at the domain registrar
1. API Integration
Please refer to these tutorials to learn how to set up API integrations with your chosen provider:
The API integration will keep your record configurations in sync between both providers. However, you are limited to only using services that are offered by both providers. For example, you cannot use some GeoDNS features with Secondary DNS since most providers do not offer an equivalent service.
2. Apply the Secondary provider to the domain
A. Within the domain, you would like to have this feature configured for, navigate to 'Advanced Settings'.
B. Select ' Secondary DNS Provider ' and choose your provider.
3. NS Records
Within your domain in Constellix, you will add Name Server (NS) records that point the domain in question to the available set of name servers belonging to the other provider.
You will then do the same at the other provider, which means that there should be 6 NS records at the external provider pointing the root domain to the following Name Servers:
3. Update your Registrar
You will also need to update your domain registrar, the same organization where you have purchased your domain from, with the nameservers of both providers, which means you will have 6 name servers from Constellix, and the remaining Name servers from the second provider.
