Hi Rowland,

I don't want to be impertinent, but what's about the second part of my 

I don't think there's an IPv6 address in play. It's just the command 
that searches for the reverse zones which is giving back also the IPv6 zone.

If then your function "rev_zone_info" gets first the IPv6 reverse zone 
it breaks the function because the name is totally other constructed.

Or am I misunderstand something?
