Entrambi i server che hai messo non possono risolvere, ma per 
ragioni differenti: il primo non ha record relativi al dominio 
(forse è ancora in fase di trasferimento):

[morriz a bellatrix:~]# host -t a brescia5stelle.org. sdns1.ovh.net
Using domain server:
Name: sdns1.ovh.net
Address: 213.251.188.140#53
Aliases:
Host brescia5stelle.org not found: 2(SERVFAIL)

----------------------------------------------------------------

Il secondo non è un server dns:

[morriz a bellatrix:~]# host -t a brescia5stelle.org. 
r33089.ovh.net
;; connection timed out; no servers could be reached

---------------------------------------------------------------

[morriz a bellatrix:~]# sudo nmap -v -v -sU -p 53  r33089.ovh.net
