DNS for SaaS
SaaS DNS is a product surface, not a registrar default.
Multi-tenant SaaS accumulates customer CNAME onboarding, vanity nameservers and regional application endpoints. Registrar DNS does not scale to that.
Host application and customer-domain zones on Cloud DNS. Use the API, vanity nameservers, health checks and low TTLs as part of the product.
Why teams use Aptranet
What DNS for SaaS looks like on this network.
Cloud DNS answers on 210+ Anycast servers, with GeoDNS, health checks and a one-second minimum TTL for change.
API-managed zones
Provision customer records without operating the DNS network.
Vanity nameservers
Present branded NS while Anycast still answers.
Regional SaaS endpoints
GeoDNS and health checks steer tenants toward a live region.
How to set it up
A cutover you can validate before DNS moves.
Create the Cloud DNS configuration, prove it on an Aptranet hostname, then point production DNS when the path looks correct.
- 1Put application DNS on Cloud DNS
The product hostname, API hostname and status page.
- 2Automate customer domain records
CNAME or flattening targets for custom domains, via the API.
- 3Add health-aware regional records
Tenants should not resolve into a down region.
- 4Offer vanity NS if you resell DNS
Optional. Most SaaS only needs CNAME onboarding.
Outcomes
What changes once the hostname is on Aptranet.
- Customer domains can be provisioned through the API
- Application DNS is Anycast and health-aware
- Vanity NS is available for branded authority
