[Unbound-users] Unexpected results - Unbound results don't match external DNS

Hi,

I don't know if I'm expecting too much from unbound but for certain lookups I get a different result from unbound than I get from an external DNS server.  For example:


Using Unbound:

# nslookup 158.24.39.46.zen.spamhaus.org. 
Server:		127.0.0.1
Address:	127.0.0.1#53

Non-authoritative answer:
Name:	158.24.39.46.zen.spamhaus.org
Address: 92.242.144.50


Using External DNS:

# nslookup 158.24.39.46.zen.spamhaus.org [external DNS]
Server:		[external DNS]
Address:	[external DNS]#53

Non-authoritative answer:
Name:	158.24.39.46.zen.spamhaus.org
Address: 127.0.0.4
Name:	158.24.39.46.zen.spamhaus.org
Address: 127.0.0.11


I actually need unbound to provide the results as given by the external DNS - same format, same answer.  The server uses the answer from the external server perfectly.  It fails when it uses unbound.  I don't see any settings in unbound.conf that might resolve this issue.  Did I miss anything?  Or is Unbound not able to provide the same results due to the 127.0.0.x answer?

Thanks!

Patrick
