The server was not stable, the same tests nslookup give different results, I noticed that by making changes in the records of the areas, are not reflected in the query response in spite of the areas that the file is changed.

Asked localhost responded: server can not find esempio.net: SERVFAIL Address: 127.0.0.1 # 53
repeated the test but has successfully responded address Address::: 1 # 53
As you can evaluate below:

Server:         localhost
Address:        127.0.0.1#53
> set q=SOA
> esempio.net
;; Got SERVFAIL reply from ::1, trying next server
;; Got SERVFAIL reply from ::1, trying next server
Server:         localhost
Address:        127.0.0.1#53

> esempio.net
Server:         localhost
Address:        ::1#53

quikon.net
        origin = dns2.esempio.net
        mail addr = admin.esempio.net
        serial = 2012012502
        refresh = 7200
        retry = 540
        expire = 604800
        minimum = 86400

I just asked myself these questions?

Tomorrow another reinstall DNS, and I'll know, Suggested you on, what to install?

Thanks for your attention
