有时我们需要检测IP输入的正确性与网络掩码的正确性,用shell脚本写的: #验证ip地址的正确性 check_ip_format() { echo $1 | grep "^[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}$" > /dev/null if [ $? = 1 ]; then return 1 else a=`echo $1 | awk -F. '{print $1}'` b=`echo $1 | awk…

468. 验证IP地址 编写一个函数来验证输入的字符串是否是有效的 IPv4 或 IPv6 地址. IPv4 地址由十进制数和点来表示,每个地址包含4个十进制数,其范围为 0 - 255, 用(".")分割.比如,172.16.254.1: 同时,IPv4 地址内的数不会以 0 开头.比如,地址 172.16.254.01 是不合法的. IPv6 地址由8组16进制的数字来表示,每组表示 16 比特.这些组数字通过 (":")分割.比如, 2001:0db8:85a…
In this problem, your job to write a function to check whether a input string is a valid IPv4 address or IPv6 address or neither. IPv4 addresses are canonically represented in dot-decimal notation, which consists of four decimal numbers, each ranging…
