displayIP alters outcome of inRange

[fishcharlie]

The following code prints false then true. Passing an IP in using rangeCheck.displayIP shouldn't alter the outcome of rangeCheck.inRange

var rangeCheck = require('range_check');
let cloudflareips = [
	"103.21.244.0/22",
	"103.22.200.0/22",
	"103.31.4.0/22",
	"104.16.0.0/12",
	"108.162.192.0/18",
	"131.0.72.0/22",
	"141.101.64.0/18",
	"162.158.0.0/15",
	"172.64.0.0/13",
	"173.245.48.0/20",
	"188.114.96.0/20",
	"190.93.240.0/20",
	"197.234.240.0/22",
	"198.41.128.0/17",
	"2400:cb00::/32",
	"2405:8100::/32",
	"2405:b500::/32",
	"2606:4700::/32",
	"2803:f800::/32",
	"2c0f:f248::/32",
	"2a06:98c0::/29"
];
console.log(rangeCheck.inRange("::ffff:172.68.34.38", cloudflareips)); //false
console.log(rangeCheck.inRange(rangeCheck.displayIP("::ffff:172.68.34.38"), cloudflareips)); //true

Recently started using this project again since using it in internal project, and converted it to Typescript. The general idea of those functions to make different varieties more IPs searchable.

::ffff:172.68.34.38 is being normalized as 172.68.34.38
https://tehnoblog.org/ip-tools/ip-address-in-cidr-range/
IP Address 172.68.34.38 is in CIDR range 172.64.0.0/13
