ホスト名がドットのみ


レンタル掲示板サービスには毎日ものすごい数のスパム投稿があるわけですが、そのスパム投稿の中に前々から気になっていることがあったのです。

ホスト名がドット(.)のみ

そんなの有り?

ドットで正引きしても当然ながらIPを引ける訳もないので、掲示板スクリプトの中にトラップを仕込んでIPを割り出してみました。

IPアドレス:92.48.122.3

逆引き結果
> nslookup 92.48.122.3

Non-authoritative answer: 3.122.48.92.in-addr.arpa name = . Authoritative answers can be found from: 122.48.92.in-addr.arpa nameserver = a.ns.as29550.net. 122.48.92.in-addr.arpa nameserver = b.ns.as29550.net.

whoisの結果
> whois 92.48.122.3
