Cloudflare: Pointing subdomains to a different droplets?

Posted May 24, 2017
DNS Networking Ubuntu 16.04

Hi,

I have my main domain.com pointing to 1.2.3.4 droplet. Now I want to set my new app.domain.com to 5.6.7.8 droplet using CloudFlare.

For this I created an A record with the name app and the value 5.6.7.8, but for some reason when I check the DNS propagation or when I ping app.domain.com, it still resolves to 1.2.3.4.

This is my current configuration:

Type Name Value TTL A app points to 5.6.7.8 Automatic A domain.com points to 1.2.3.4 Automatic A www points to 1.2.3.4 Automatic

Any idea of why this may be happening?

Generally what I’d recommend setting up is:

A          domain.com   DROPLET_01_IP
CNAME      www          domain.com

A          app          DROPLET_02_IP
CNAME      www.app      app.domain.com

DROPLET_01_IP = 1.2.3.4

DROPLET_02_IP = 5.6.7.8
