批量ping连续ip

今天需要新开一个vlan，准备给用192.168.12.0/24网络，测试下这个段ip有没有被使用，批量ping下这个网段
写了一个脚本：

[root@xiaoxuan ~]# cat ping.sh 
#!/bin/bash
if [ -z "$1" ];then
    echo -e "\033[40;33mUsage: /bin/bash ping.sh 192.168.16\033[40;37m"
    exit 1
fi

for ((i=1;i<=254;i++));do
    ping  -c 1 $1.$i > /dev/null 2>&1
        if [ $? -eq 0 ];then
            echo -e "\033[40;32mThe server "$1"."$i" status is UP\n\033[40;37m"
        else
            echo -e "\033[40;31mThe server "$1"."$i" status is DOWN\n\033[40;37m"
        fi
done
[root@xiaoxuan ~]#  ./ping.sh 
Usage: /bin/bash ping.sh 192.168.16
[root@xiaoxuan ~]#  ./ping.sh 192.168.13
The server 192.168.13.1 status is UP

The server 192.168.13.2 status is DOWN
