ipaddr.js believes that every numerical value can be interpreted as an IP address

I need a way to determine if the input string is an IP address, and return true if it is.

My current function using ipaddr.js library looks like this

import * as ipaddr from 'ipaddr.js';

function isIpaddress(ip) {

return ipaddr.isValid(ip);
}

Surprisingly, this method returns true even for any number passed into it. As a first-time user of ipaddr.js, I expected .isValid to perform all necessary checks automatically.

If anyone can offer assistance or explanation on why this behavior occurs, I would greatly appreciate it. Thank you.

Answer №1

It is important to note that any valid unsigned 32-bit integer can be considered as a valid IPv4 address.

> Converting an array of [192, 168, 0, 1] into a buffer results in <Buffer c0 a8 00 01>
> By reading the unsigned integer at index 0 in the buffer, we get 3232235521
> Using 'ipaddr.js' to parse this integer provides us with IPv4 address { octets: [ 192, 168, 0, 1 ] }
> However, attempting to parse '99999999999' using 'ipaddr.js' will result in an error message stating that the address does not have either an IPv6 or IPv4 format.
