BIND 9 - I'm not sure is working correctly!

NO (because in this case BIND is not involved, I think)

You are absolutely right ! As I said in RH 7.0 or previous I also get the
same
result with or without adding "-n" at ping.

Now, Why I said I'm not sure ? :

I've installed a clean RH 7.1 (BIND 9.1.0), then I added my config and zone
files (which I verified and they are correct) then I observed that packet
lose at
"ping www.mydomain.com" then I upgraded to BIND 9.1.1, .... the same
problem. Then I added "in-addr.arpa zone" (just to test because normally
I can not do that because I don't have an entire C class) and then I issue
"ping -c 25 www.mydomain.com" and that's working just fine. So, If I remove
"in-addr.arpa zone" is working fine, if and only if I issue "ping -n".

So you may think this is in fact regarding to ping. Maybe, maybe not, Why ?
I downgraded to BIND 8.2.3 (on RH 7.1) and guess what.... there is no packet
lose when I issue a simple "ping www.mydomain.com", ("-n" option is not
necessary) !

Then I try this: I installed a clean RH 7.0 and upgrade only BIND to 9.1.1
and there is no packet lost (there is no difference between "ping -n
www.mydomain.com" and ping www.mydomain.com. Hmm.

I think this problem is confusing enough, I've checked docs, FAQ, and this
list archive and no one reported this problem. Now I know why:

If BIND 9 runs on RH previous to 7.1 there is no problem. They are going to
see this problem when they will start running BIND 9 on RH 7.1.

P.S. BIND 9 on Mandrake 8 have the same problem.

So, any idea ???
