Code:
while read LINE
do
        ans_dump "${LINE}" channel=dnsw32
done < inputfile

Depending on how ans_dump works it may be possible to run it fewer times, cramming more input into it, which would be more efficient, but I don't know anything about ans_dump. Can you put channel=... before the rest instead of after? Will it accept more than one name after it and do what you want?

Also, if you want to run grep on the output, you can do it collectively:

Code:
while read LINE
do
        ans_dump "${LINE}" channel=dnsw32
done < inputfile | grep whatever
