Linux Ping certain range of ip address

hey guys,
In my program i am giving an initial ip & end ip.
i just want to check every ip in that range is pingable or not

Code:
echo "Enter the initial ip:"
read inip
echo "Enter the end ip:"
read endip
for (( i=0; i<=$endip; i++ ))
do
if ping -c 4 $inip
then
echo "pingable"
else
echo "not pingable"
fi
done
echo "Done"

my initial ip is 172.30.36.1
my end ip is 172.30.36.10
How do i increment the last digits in a loop
