The domain name is abc.def
The web application hosted is "GHI.abc.def"
I want to host the web application as "GHI.JKL.MNO"
Is this possible, because when we add the name of the web application as an A record in DNS it will be "GHI.abc.def"
Is it possible to achieve "GHI.JKL.MNO" as the web application name, and how would I add it in the DNS
Should I extend the web application? or do a redirection to the URL?
Can I add this as an AAM?
