today, somebody decide to scan my not usable routed /64 prefix. I dont't use it and don't have specific route for it. the packet arived to my router, router lookup up in routing table for /64 prefix and send it to default route, back to you 1/128 then there is a route loop....

Everyone gets a /64 by default.  If you don't need it, don't use it.
