So I've got a domain registered with Dreamhost, which apparently does not do recursive lookups, and an app on Heroku. Heroku apps are always configured to use a CNAME record to
Authoritative DNS: ns1.dreamhost.com (for foo.com) CNAME record: app.foo.com -> proxy.heroku.com Resolves to: Set of A records for EC2 IPs
I've been told by some folks trying to connect to the app from behind a Windows Server 2003 DNS Server that it handles SERVFAIL differently and cannot resolve the DNS. I'm trying to understand if this is truly a configuration issue on my side or theirs, notably, per the title:
Must the authoritative DNS server for a domain be recursive to allow CNAME records pointing to other domains?
