We received a message about not using static IP addresses for DNS A records for our domains. We do use the proper CNAME for our www. CNAME records, but still use an IP address for the root domain, which is configured as a redirect to www. Is this configuration supported or does it need to be changed? Our current DNS provider does not support using FQDN on A records, only IP addresses.

Our A record is set to the IP address which the Netsuite CNAME resolves to and has been set that way for around 8 years.
