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
How it works with Aptranet
Cloud DNS combines Anycast resolution with traffic steering and health checks. Growth and Business support TTLs as low as one second.
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
Validate your setup before production changes.
Configure your Cloud DNS zone and verify its records and routing policies. Test answers from the authoritative nameservers before changing your domain delegation.
- 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.
