.com と.net のミススペルに気を付けよう
どっちかとういと、技術ネタなのですが、あるドメイン名管理会社(VeriSign)が設定方針をかえたため、Webをつつくときに、たとえば、ミススペルしたときとかに、今までは「そんなドメイン無い」と言われていたドメインが、VeriSignのWebページに行ってしまいます。
技術的には、Wildcard A レコードというのが登録されることになります。
彼らは、改善だといっていますが。。。大顰蹙ですな。
以下のようなアナウンスが出ています。

| Subject: Change to .com/.net behavior
|
| Today VeriSign is adding a wildcard A record to the .com and .net
| zones. The wildcard record in the .net zone was activated from
| 10:45AM EDT to 13:30PM EDT. The wildcard record in the .com zone is
| being added now. We have prepared a white paper describing VeriSign's
| wildcard implementation, which is available here:

|
| By way of background, over the course of last year, VeriSign has been
| engaged in various aspects of web navigation work and study. These
| activities were prompted by analysis of the IAB's recommendations
| regarding IDN navigation and discussions within the Council of
| European National Top-Level Domain Registries (CENTR) prompted by DNS
| wildcard testing in the .biz and .us top-level domains. Understanding
| that some registries have already implemented wildcards and that
| others may in the future, we believe that it would be helpful to have
| a set of guidelines for registries and would like to make them
| publicly available for that purpose. Accordingly, we drafted a white
| paper describing guidelines for the use of DNS wildcards in top-level
| domain zones. This document, which may be of interest to the NANOG
| community, is available here:
