Request support for CDN, which means setting up parent node resolution

Usage Scenario

In order to protect server A, a front-end CDN has been set. At this time, the DNS IP is dynamic, so this IP needs to be set with a front-end resolution server, such as

aiden.ns.cloudflare.com

journey.ns.cloudflare.com

Thus returning the dynamic IP address
