Thanks Cricket and Marc,

That accounts for the second and third Z bits. The first Z bit remains
unused, from what I can tell (checking with 
http://www.networksorcery.com/enp/protocol/dns.htm). I think I'm happy
enough now to shout at the vendor. I *think* they're trying to set RD,
but are two bits off.

Thanks all,
