求IP正则表达式 0.0.0.0不能通过跟255.255.255.255

Question

也不能通过
/^(25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[1-9])\.(25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[1-9]|0)\.(25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[1-9]|0)\.(25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[0-9])$/  
这个正则不能输0.0.0.0
/^(?!^255(\.255){3}$)(\d|[1-9]\d|1\d{2}|2[0-4]\d|25[0-5])(\.(\d|[1-9]\d|1\d{2}|2[0-4]\d|25[0-5])){3}$/g;
这个不能输入255.255.255.255
我想要两者的增合体啊 
分数够 马上结贴··

Answer 1

/^(\d|[1-9]\d|1\d{2}|2[0-4]\d|25[0-5])(\.(\d|[1-9]\d|1\d{2}|2[0-4]\d|25[0-5])){3}$/g

Answer 2

var reg = /^(\d{1,2}|[01]\d{2}|2[0-4]\d|25[0-5])(\.(\d{1,2}|[01]\d{2}|2[0-4]\d|25[0-5])){3}$/
var data = ['192.168.1.1','255.255.255.255','0.0.0.0','123.1.1.1','0.0.0','256.1.1.1','0.0.0.0.0','1.150.256.11'];
for(var i in data) {
document.writeln(reg.test(data[i]));
}
