to map a domain name to a site in my multisite network, do

Hi to map a domain name to a site in my multisite network, do I only need to add a A record to the IP of my multisite or do I need also a CNAME or other things? my user wants his website to be on http://souq.world. I added the A record directly from the registrar as this:

Name	souq.world
Class	IN
Type	A
Status	Active
Value	(IP of my multisite, read in Network settings/  Domain Mapping)
TTL	14400

but it is not accepting the mapping, it has been 1h but I know it can take longer.
thank you!
