Thanks Hector. The link you provided requires an ALIAS record, which is apparently not supported by Cloudflare. I can only add CNAME records, with the limitation of only using an IP address and not a URL.
My understanding of RFC approved records contained within a DNS zone is that A and AAAA records should contain only IP addresses for which the domain is Authoritative. CNAME records should be used when one is pointing to a DNS record in another zone for which the current zone is non-Authoritative.
So, while adding an A and a AAAA record with the “gateway.ipfs.io” IP addresses should function… it’s not strictly “correct” per RFC standard methods. Using A and AAAA records in this way may lead to incorrect routing if… for example… the external zone changes its zone file IP addresses.
But perhaps things have changed… and my understanding is no longer accurate.
