Doh! I've sent a wrong version of script, with errors. Here's a correct one:
#!/bin/bash
NET=192.168.111
HOST=example.com
LIMIT=254
for ((i=1;i<= LIMIT ; i++))
do
IP=`echo $NET.$i`
ARPA=`host $NET.$i | awk '{print $5}'`
FIRSTOCT=`echo $IP $ARPA | grep NX | awk '{print $1}' | cut -d .
-f1`
SECOCT=`echo $IP $ARPA | grep NX | awk '{print $1}' | cut -d .
-f2`
THIRDOCT=`echo $IP $ARPA | grep NX | awk '{print $1}' | cut -d .
-f3`
LASTOCT=`echo $IP $ARPA | grep NX | awk '{print $1}' | cut -d .
-f4`
PTR=`echo host$LASTOCT.$THIRDOCT.$SECOCT.$FIRSTOCT.$HOST | grep
-v 't\.'`
echo $LASTOCT.$THIRDOCT.$SECOCT.$FIRSTOCT.in-addr.arpa. IN
PTR $PTR. | egrep -v '^\.'
done
