options
are passed to it.

Params
ip
{string} - Accepts only valid IPs by defaultpatterns
{string|array} - Basically everything that micromatch's second argument can accept.options

import ipFilter from 'ip-filter';
console.log(ipFilter('123.77.34.89', '123.??.34.8*')); // => '123.77.34.89'
console.log(ipFilter('123.222.34.88', '123.??.34.8*')); // => null
console.log(ipFilter('123.222.33.1', ['123.*.34.*', '*.222.33.*'])); // => '123.222.33.1'
// should notice the difference
console.log(ipFilter('123.222.34.88', ['123.*.34.*', '!123.222.**']));
// => null
console.log(ipFilter('123.222.34.88', ['123.*.34.*', '!123.222.*']));
// => '123.222.34.88'

import ipFilter from 'ip-filter';
//
// NON-STRICT mode
