Creaing a CNAME record versus A name for customers of a SaaS application
When using cloudflare DNS for a SaaS application, is telling customers to point to my DNS, if I tell them these 2 options, are they the same?
1) ip address (A record )
2) customer123.SaaSWebsite.com CNAME (this way if my SaaS applications ip address changes, I don't have to tell all customers to change their DNS)
Are their any issues with #2 option?
