interpreting dlint

Hi,

when I run dlint on my scaledesk.com domain, I get 6 errors. All of them is that ?.scaledesk.com is A record for 72.14.187.96, but PTR record for 96.187.14.72.in-addr.arpa. is "scaledesk.com."

Dlint further recommends using CNAMEs for all. I'm by no means DNS expert, but should domain be allowed to have as many A records as needed and they are faster to resolve than CNAMEs?

Should I change something or just ignore the errors?

Thanks…
