Thanks, I'm looking how solve this, cleanly.
In my country only 1 ISP have IPv6, then I need keep IPv4.
I have 1 IPv4 for 1000 VPS, no way here to have more IPv4.
Then:
1) I'm not sure if my DNS authoritative on IPv6 reply correctly (but reply
correctly to all my dig query)
2) I have to provide a way to my customer can resolve query on their DNS server
on their IPv6 VPS, their need be able to just put their vps dns or at least
common server dns (where I had to put their zone, then I dislike this idea)
For now your method fail, include I try:
zone "ore.org.bo" {
type master;
file "/etc/bind/ore.org.bo.db";
};
But failed too.
Well I didn’t say to do that. You have they wrong type of zone. Make it a
secondary (slave) zone
like I told you to do.
zone ore.org.bo {
type secondary;
file “ore.org.bo.db”;
primaries { 2803:1920::c:1963; };
};
Now that should work as I can AXFR the zone from that server. You should also
note the difference in
the flags in the responses for smtp.ore.org.bo. The one from 2803:1920::c:1963
is an authoritative
reply (aa) and the TTL stays at 3600, whereas the one from 45.225.75.8 is not
(aa is not set in the
flags) and the TTL decreases indicating that it comes from a recursive server.
It also looks like someone tried to comment out *.ore.org.bo but used the wrong
comment character ‘#'
rather than ‘;’.

Because the customer are into IPv6 zone
Well all zones should be served by both IPv4 servers and IPv6 servers. IPv6 is
nearly 30 years old now. There are
sites that are IPv6 only because they would prefer to not have to run
everything through 2 or 3 layers of NAT when
they don’t need it at all for IPv6 and would really like to not have to send
all there DNS queries though NAT64 boxes.
And the EDGE router connecting IPv4 and IPv6 is internal to the data center
company, not accessible for the customer.
Forward zone to edge will be more complex, it's more simple just forward the
query.
Thanks for you observation, but I know, I doing this quickly, I will keep like
this for now, this will produce only problem for availability if the server is
down.
Except you are wrong. You are writing here because it *is* causing you and
everyone else a problem. The correct way to
fix this is to transfer the zone contents to the listed primary servers if you
are using nameservers. Alternatively
don’t run nameservers at all but use IP level proxies. Either the whole address
or port forward 53/TCP and 53/UDP.

Why don't you simply run multiple authoritative servers, some only
accessible by IPv6, some dual-stack?
They are independent of each other and only the zone transfer need to
work.
I also see some strange things:
m@ryz:~$ host 811.vps.confiared.com.
811.vps.CONFIARED.com has address 45.225.75.8
811.vps.CONFIARED.com has IPv6 address 2803:1920::c:1963
m@ryz:~$ host 811b.vps.confiared.com.
811b.vps.CONFIARED.com is an alias for 811.vps.confiared.com.
811.vps.CONFIARED.com has address 45.225.75.8
811.vps.CONFIARED.com has IPv6 address 2803:1920::c:1963
m@ryz:~$
You should have redundant servers and not 2 NS records that point to
the same machine.
Please fix that first and update your glue records.
