 ## Background
 Currently, Kusaba X and a lot of Kusaba X ports use a very insecure algorithm for calculating "Poster IDs". That is, a semi-unique ID used as a means of identification. Unfortunately, the developers must have overlooked the major flaw in the algorithm when developing the function. The poster IDs are calculated by simply truncating an (unsalted) MD5 hash of the dotted decimal representation of the user's IP address to 6 characters. As there are 2<sup>32</sup> IPv4 addresses and only 2<sup>24</sup> possible IDs, it makes it possible (and incredibly easy) to narrow an ID down to ~256 IP addresses. The rest could possibly be eliminated using GeoIP or any other means.
