N2 - It is known that some of the unassigned IP addresses are announced as legitimate routes, even though they are never assigned to any end-user. The reason for this is that the current routing system of the Internet with BGP allows unassigned IP addresses to be announced as well. On the other hand, actual situation is still unclear and there is no solid method for such an investigation. Thus, we conducted the very first investigation in Japan and proposed a simple and effective method. In our proposed method, we compare the address pool delegated to Japan and the actual route information that is available online. As a result, we have revealed that some unassigned IP addresses had been announced from both within Japan and overseas for several years because of human-setting-error. These problems affect not only registries, ISPs or carriers but also general end-users as well.
