dns - Why using A record for OpenShift is bad idea? -

-

if ping openshift application see ip

ec2-11-22-33-44.compute-1.amazonaws.com [11.22.33.44]

can sure ip 11.22.33.44 , can use record in dns settings?

in cases ip changed ?

never seen inforamtion. articles claim cname may work.

you should never use record point openshift application external domain. ip address can change @ time outage or maintenance reasons. should use cname point domain name application url of format app-domain.rhcloud.com
