I got many private and public replies so I will briefly summarize the 
answers and the solution :

At first, the problem comes from the fact that Bind is using IPv6 while 
our system and network don't use IPv6 at all.

Therefore the solution is to remove IPv6 support from Bind.
That's easy, an option "-4" (IPv4 only) had to be added at startup.

I added OPTIONS="-4" to /etc/sysconfig/named and now it doesn't complain 
anymore about IPv6 :-)

Thanks a lot to everyone
