Check if a string is an IP address
npm install is-ip> Check if a string is an IP address
If you only need this for Node.js and don't care about browser support, you may want to use net.isIP instead. Note that it returns an integer instead of a boolean.
``sh`
npm install is-ip
`js
import {isIP, isIPv4} from 'is-ip';
isIP('1:2:3:4:5:6:7:8');
//=> true
isIP('192.168.0.1');
//=> true
isIPv4('1:2:3:4:5:6:7:8');
//=> false
`

Check if string is IPv6.

ipVersion('1:2:3:4:5:6:7:8');
//=> 6
ipVersion('192.168.0.1');
