Problems with past arguments in script

I have a question is there any possibility for maken a script that you can see if computers are on in your network
when you run the script for ex. ./ping.sh 54 62 62 , a script when you give as argument the last digit of the ip adres of the computers

my network is 192.168.129.0

This is what i already have but i want to give extra parameters to the script
for example
parameter 1: xx-yy: this parameter ensures that all computers be test in the range of xx-yy eg. 61-67, test all the 7 computers with the last digit

parameter 2: -t , ensures that each number count with 200 eg. -t 17 test the ip adress 217 , -t 17-19 test all the adresses 217 to 219

1. for ip in192.168.1.{1..10};do# for loop and the {} operator
2. ping -c 1-t 1192.168.1.1>/dev/null 2>/dev/null # ping and discard output
3. if[ $?-eq 0];then# check the exit code
4. echo "${ip} is up"# display the output
5. else
6. echo "${ip} is down"
7. fi
8. done

 

I use:

Code:

#!/usr/bin/env bash

network=${1}

is_alive()
{
    ping -b -c 1 ${i} > /dev/null
    [[ $? -eq 0 ]] && echo "${i} is up"
}

for i in ${network}.{0..254}
do
    is_alive ${i} & disown
done

./ping.sh 10.0.0
