Hello,
first I would like to thank you for your great job with NicTool. Now to the point: I have successfully imported all of zones except rDNS IPv6 ones. I was looking all around tnpi forum for any clue without success (where my account has not been approved yet).

Resending error:

bind test config file includes this:
zone "e.3.2.0.0.3.4.0.1.0.a.2.ip6.arpa." {
type master; allow-query { any; };
file "/tmp/ipv6";
};

My zone:
$TTL 300

2016051601 ;Serial
7200 ; Refresh

7.4.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0 PTR mail.dathen.com.

Well, zone is created without any problem but after it its stucked on adding NS i guess. I would be very glad for any comment on this.
Thank you !
