Edge Security Acceleration:DNS

DNS setups

• CNAME: Suitable for large enterprises that use multiple proxy acceleration services simultaneously. Choose CNAME setup if different subdomains of your website (such as api.example.com, img.example.com) use different cloud services, and you only want to connect some subdomains to ESA. Configure the CNAME record generated by ESA at your DNS service provider.

• NS: Suitable for individual developers and small to medium-sized enterprises. Choose NS setup if you want all DNS records under your website (such as example.com) to be managed and accelerated in a one-stop manner. Change your domain's DNS server address to the NS address assigned by ESA. ESA will take over your DNS configuration, and you will need to manage your DNS records in the ESA console.

Feature overview

Through the DNS management, you can perform the following configurations on your website:

• DNS analytics

  DNS analytics provides key metric monitoring and traffic statistics reports in the form of visualized analytics with different dimensions. You can adjust service policies based on the real-time monitoring for your website.

• Manage DNS records

  After adding your website to ESA, you can manage DNS records in the console.

• CNAME flattening

  CNAME records cannot coexist with other record types (such as MX or TXT) under the same root domain name due to DNS protocol limitations. CNAME flattening resolves these conflicts by mapping CNAME records to their IP addresses and returning the IP address of the target domain instead of its CNAME record. This feature also reduces recursive queries by local DNS, speeding up domain name resolution for clients.

• Convert DNS setup

  This topic guides you through the steps to convert your DNS setup from NS to CNAME or vice versa.
