I'm not sure why BIND would flag this as a "bad referral". Seems like the remote nameserver is answering correctly, given that it is non-recursive and the closest ancestor to the CNAME target that it knows about is the "net" TLD. How should it answer differently?

I noticed that (see the dig at the end of this post) www.symantec.com. is CNAME to www.symantec.d4p.net (and in turn CNAME to 1568.g.akamai.net). So I roughly understand why it refers my nameserver to net. But why there is an error in the log? How do I stop logging this error? Or is it something wrong with my nameserver?
