no hostname become unresolvable.

[Cefull Lo]

Hi everybody,

I just setup my dns using bind-9.6.1-P2

when I try to ping the server with a hostname, that's ok.
i.e.
#ping www.superease.net
PING www.superease.net (202.68.195.36) 56(84) bytes of data.

But when I try to ping the server without hostname,

#ping superease.net
ping: unknown host superease.net

Can someone tell me what's up?!?!?!?

Here the zone file

$TTL    86400
$ORIGIN superease.net.
