[英]Javascript calculate IPv6 range from CIDR prefix
Using Javascript (without JQuery) I'm looking to get the minimum and maximum IPs in a IPv6 CIDR prefix. 我正在使用Javascript(不使用JQuery)来获取IPv6 CIDR前缀中的最小和最大IP。
For example, 2001:280::/32
would output 2001:280:0:0:0:0:0:0
and 2001:280:ffff:ffff:ffff:ffff:ffff:ffff
. 例如
2001:280::/32
将输出2001:280:0:0:0:0:0:0
和2001:280:ffff:ffff:ffff:ffff:ffff:ffff
。
How can I do this? 我怎样才能做到这一点? Thanks in advance!
提前致谢!
Assuming you have Node and NPM installed: 假设您已安装Node和NPM:
$ touch index.js
$ npm init
$ npm i --save ip-address
$ vim index.js
var v6 = require('ip-address').v6;
var addr = new v6.Address('2001:280::/32');
console.log(addr.parsedAddress.join(':'));
console.log(addr.endAddress().address);
$ <esc>:wq
$ node index.js
2001:280:0:0:0:0:0:0
2001:0280:ffff:ffff:ffff:ffff:ffff:ffff
There doesn't seem to be a browser facing package so I'd suggest using Browserify ( http://browserify.org/ ) to get this to work or fork the project and stuff everything into one file so you can run it in your browser (leaving out the node-specific code, of course). 似乎没有面向浏览器的软件包,所以我建议使用Browserify( http://browserify.org/ )使它工作或将项目分叉并将所有内容填充到一个文件中,以便您可以在自己的文件中运行它浏览器(当然,省略了特定于节点的代码)。
Try the ip6
npm package: https://www.npmjs.com/package/ip6 尝试
ip6
npm软件包: https ://www.npmjs.com/package/ip6
ip6
helps to normalize, abbreviate, divide subnets, generate random subnets/hosts and calculate range of size of an IPv6 subnet. ip6
有助于规范化,缩写,划分子网,生成随机子网/主机以及计算IPv6子网的大小范围。
let ip6 = require('ip6');
console.log(ip6.range('2001:280:0:0:0:0:0:0', 32));
{ start: '2001:0280:0000:0000:0000:0000:0000:0000',
end: '2001:0280:ffff:ffff:ffff:ffff:ffff:ffff',
size: 7.922816251426434e+28 }
Or in command line: 或在命令行中:
ip6 -R 2001:280:0:0:0:0:0:0 32
{"start":"2001:0280:0000:0000:0000:0000:0000:0000","end":"2001:0280:ffff:ffff:ffff:ffff:ffff:ffff","size":7.922816251426434e+28}
