You can map as many domains as you want using the domain mapping feature.
Go to General Settings (Under the “View My Site” drop-down menu in the top right) > Domain Mapping to configure it.
1.) Go to your domain provider DNS Manager and create a CNAME record.
2.) Return to the Domain Mapping settings page and type in the domain name and click add.
3.) Repeat step 2 for your domain with and without “www.” in front of it.
If your domain registrar doesn’t allow CNAME records, you can use A and AAA records instead (you’ll need to add both).
Here are the records you can add to your DNS manager.
CNAME record:
stratinuity.com
A record:
138.197.73.102
AAAA record (optional for IPV6 support):
2604:a880:800:10::beb:6001
CNAME (optional for wildcard support):
CNAME record:
Hostname: _acme-challenge
Value:
_acme-challenge.stratlevelup.tempurl.hos
