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

Hmmm. Interesting.
In the second case, if you do a simple:
## Rh 7.1 (with BIND 9.1.1)
# ping -c 25 193.230.52.100
Do you get any packet loss?
I'm really kinda confused about the "-n" option. I'm not sure what:
"No attempt will be made to lookup
symbolic names for host addresses.
"
really means -- on my RH6.2 system I get the same output with or without
"-n" :|

Subject: BIND 9 - I'm not sure is working correctly!
I'm asking this because I just upgraded from RH 7.0 to RH 7.1. BIND 9.1.0/1
is
acting very strange on RH 7.1 (having exactly the same config and zone
files).
On RH 7.0 (with BIND 9.1.1) -> ping -c 3 www.comefnet.com
PING www.comefnet.com (193.230.52.100) from 193.230.52.100 : 56(84) bytes of

I think the ping binary is also modified because is working fine IF AND ONLY
IF:
1. I add "in-addr.arpa" zone for my domain (very hard because is not an
entire C class) or
2. I use ping -n www.mydomain.com (-n disable host lookup) or
3. I use BIND 9.1.1 on RH 7.0 and use the ping that comes with RH 7.0.
So "ping" that comes with RH 7.1 needs "-n" to work.
"nslookup" and "dig" are working fine returning correct info, and LAN
clients don't have
problems with DNS and they are UNIX and Win9x.
After all this my question is:
How can I be sure BIND 9 is working correctly ?
