return code from host command

When I do a host command on a remote machine (not the DNS server), host
gives me a return code of 0 even when the machine is not found.  When I
do the identical command on the DNS server I get the same answer, but
the return code is 1, which is what I would have expected.  Why?

NOT ON THE DNS SERVER

$ /opt/ISCbind/bin/host 165.168.235.199 pwdnsrev1.is.bear.com

Using domain server:

Name: pwdnsrev1.is.bear.com

Address: 147.107.87.3#53

Aliases:

 

Host 199.235.168.165.in-addr.arpa not found: 3(NXDOMAIN)

$ echo $?

0

$ echo $SHELL

/bin/ksh

$

ON THE DNS SERVER

pwdnsrev1# /opt/ISCbind/bin/host 165.168.235.199 pwdnsrev1.is.bear.com
