I can see how all those would match, why don't you think so? Here's the first one you thought shouldn't match broken down 210-20-54-173.rev.home.ne.jp matched pattern *-*-*-*.home.ne.jp * matches 210 - matches - * matches 20 - matches - * matches 54 - matches - * matches 173.rev ..home.ne.jp matches .home.ne.jp
