What Are the Differences Between the Old and New CNAME Records?
Background
WAF upgrades CNAME records to improve the reliability of domain name resolution.
To minimize the impact caused by CNAME record changes, WAF displays the old and new CNAME records on the basic information page.
Differences Between Old and New CNAME Records
The new CNAME record uses two heterogeneous active-active DNSs, improving the reliability of domain name resolution.
It is recommended that you select a new CNAME during domain name resolution.
