How to get IP to configure "A" DNS?
000webhost does not support direct IP access.
You could point your domain to 000webhost instead:
Or how to set the "MX" values in the cpanel.
For this feature to work, make sure your domain is parked to 000webhost first.
If so, please go to 000webhost cPanel > Set web address > locate your domain > Manage > Set MX record
