So the script just sends an IPv4 address, this means that the IPv6
address must be coming from this line:

PTR_REC=$($SAMBATOOL dns query ${Server} ${revzone} ${IP2add} PTR
$KTYPE 2>/dev/null | grep 'PTR:' | awk '{print $2}' | awk -F
'.'
'{print $1}')

The samba-tool dns query must be returning an IPv4 AND an IPV6 address,
I think I need to use an array and use that to discard any IPv6
addresses.

Now I know what the problem is, I can work on fixing it.

Hi Rowland,

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

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?
