判断某一ip地址是否属于某一ip网段的脚本

IPLIST=$(cat ip) NETLIST=$(cat network)   for ip in ${IPLIST} do   echo "IP: $ip";   for network in ${NETLIST}   do     [ "$(ipcalc -n $ip/${network#*/})" = "$(ipcalc -n $network)" ] &&                               echo -e "$ip/tis in $network" ||                               echo -e "$ip/tis not in $network"     done   echo "--------------------------------"; done

1 使用了for双循环

2 利用ipcalc来判断ip地址的网络地址与此网段是否一致
