Definition
What it is
A domain is the human-friendly name people type to reach your app. You rent it yearly from a registrar, then point it at your app's host using settings called DNS records.
A subdomain is a prefix on a domain you own: app.acme.com or help.acme.com. It's common to keep the marketing site on acme.com and the app on app.acme.com.
DNS changes can take minutes to a few hours to spread across the internet.

How to ask for it
Vague
“I want it to have a normal web address.”
Why it works
"A normal web address" leaves the name and setup open; naming the domain and subdomain makes the configuration exact.
