Actually, there's no tool to query DNS information from a script. People tried to use host(1) but its output have to be parsed and it is inconsistent, too. I wrote dnsget utility exactly for this purpose - to be able to query DNS information from a script, and to be able to do DNS debugging more easily -- it is part of UDNS software, http://www.corpit.ru/mjt/udns.html . It is not packaged for Debian. If you _only_ need hostname-to-ip-address translation, like it looks like you do, -- yes, a tool like getent should be sufficient. But busybox does not provide such applet (yet). But really, what's up with in-kernel DNS client these days, shouldn't kernel be able to perform such translation automatically?
