I have to go home soon, so here's a quick and dirty shell script that should
work (uses ipcalc):
#!/bin/bash
cat TEST-A.txt | while read LINE
do
RANGE=`echo $LINE | cut -d';' -f1`
echo `ipcalc -n $RANGE | grep "^HostM" | awk ' { print $2 } ' |
awk -F. -v r=$LINE ' { print r" "$1*16777216+$2*65536+$3*256+$4; } '`
|
while read INTRANGE
do
set $INTRANGE
echo $1
cat TEST-B.txt | while read ANIP
do
INTIP=`echo $ANIP |
awk -F. ' { print $1*16777216+$2*65536+$3*256+$4; } '`
if [ $INTIP -ge $2 -a $INTIP -le $4 ]; then
echo " "$ANIP
fi
done
done
done
=>
63.31.63.0/24;9007;44536
63.31.63.2
63.31.63.66
64.65.0.0/19;9000;8263
62.64.14.0/21;9001;6852
62.64.14.231
