<div>Hi,</div>
<div> </div>
<div> Our setup is; We have internal DNS server wherein
BIND is configured in RHEL 5 and many internal zones are
configured. if Internet connection is down, our Internal
DNS severs are not able to get the DNS query from ISP
DNS server. Because of this, all users are not able to
access many critical application hosted in internet.</div>
<div> </div>
<div> Now we would like to add those critical applicaton
DNS entries in our internal DNS server HOST file. So
that if internet link is down, users will be able to get
the IP address of the URL through host file.</div>

If the names of these "critical applications" reside in zones that
you own, you should probably set yourself up as a stealth slave for
those zones. If they're in someone else's zones, and being a stealth
slave is impractical, then you could play a dangerous game by
maintaining a "fake" version of the zone yourself (defined as
"master"). Dangerous because the IPs could change without any notice
and then your data is instantly invalid. But, I suppose that isn't
any worse than hosts-file entries, right?<br>

Nope, BIND doesn't control whether a process looks in the hosts file
or not.<br>
