Whois検索

This is a free service for checking information
about ownership of a domain name.
ドメイン名, IPアドレスの所有権についての情報を確認します。


ドメイン名・IPアドレスを上のテキストボックスに入力して検索して下さい

メモ

検索結果については各Whoisサーバの返答をそのまま表示。
Whoisサーバによっては返答しない、返答が遅い場合がある。(結構多い)
一部のWhoisサーバでは、検索を繰り返すと以後暫く検索できなくなる場合がある。

日本語ドメインなどは自動的にPunycodeに変換するので日本語ドメイン名そのままで検索して問題ない筈。
IPアドレスは一部の範囲を除き検索できる。

2016年4月13日時点で1196種類のTLD(トップレベルドメイン)とWhoisサーバの組み合わせを登録。
TLDが膨大に増えているので新しいものを追いきれていない場合がある。
新しくないTLDでもWhoisサーバが不明で検索できないドメインがある。

実在するドメインで検索できなかったものがあれば下のメールアドレス宛にそのドメインをお知らせ下さい。(本文はドメイン名だけで構いません)対応できるものは逐次対応。Whoisサーバが不明なものについては対応できない場合もあり。
