Bind logs

[Simona Forgione]

Hi everyone,

it's the first time I write in this mailing-list, and I hope someone can
help me.
I'm having some "strange" logs like those:

Jun 14 00:03:02 dns named[65]: unapproved update from
[195.191.2.95].4203 for rossinitravel.it
Jun 14 00:03:45 dns named[65]: unapproved update from
[194.247.162.206].4288 for atitalia.com

My name server (dns.flashnet.it 194.247.160.1) is authoritative for 
rossinitravel.it and atitalia.com,
what are 195.191.2.95 and 194.247.162.206 trying to do?


Thanks in advance,

Simona Forgione
