.ac.jpのドメインリストをダウンロードする方法

.ac.jpの完全なドメインリストは、1つの構造化ファイルとして提供されています。リストの各エントリは、完全なレコードとともにエクスポートされた登録済みドメイン1件です。自分でクロールする代わりに、すべてオフラインで処理できます。

用途に合ったデータセットを選び、.ac.jpのリストをJSONL形式（zstd圧縮）でダウンロードしてください。これは当社のAPIを支えているものと同じリストです。購入前にリストの無料サンプルを利用でき、アクセス期間中はいつでも最新のエクスポートを再ダウンロードできます。

.ac.jpの各リストには、ドメインごとに次の情報が含まれます：

リスト全体のDNS、RDAP、WHOISレコード、レジストラ、各種日付。
リスト内の各サイトで検出された技術。
ホスティングIP、国、PageRank / Harmonicランキング。
毎日更新されるエクスポートなので、受け取るリストが古くなることはありません。

よくある質問

.ac.jpドメインはいくつありますか？

webatlaは4K件のアクティブな.ac.jpドメインを追跡しており、毎日再エクスポートされます。各ドメインにはDNS、RDAP/WHOIS、検出された技術、IP、ホスティング国、ランキングが含まれます。

.ac.jpドメインの完全なリストをダウンロードできますか？

はい、.ac.jpの完全なリストは構造化されたJSONL（zstd）としてダウンロードできます。まず無料サンプルをご利用いただけます。

各ドメインにはどのような情報が含まれ、どのくらいの頻度で更新されますか？

すべてのドメインに完全なスキーマ（DNS、RDAP/WHOIS、技術、IP・国、PageRank、Harmonic）が含まれ、毎日再エクスポートされます。

.ac.jpのドメインリストはどうやってダウンロードしますか？

データセットを選択すると、.ac.jpの完全なリストが1つのJSONLファイルとしてアカウントに届きます。1か月のアクセス期間中はいつでもリストを再ダウンロードでき、まず無料サンプルもダウンロードいただけます。

.ac.jpのリストはどのような形式ですか？

リストはzstdで圧縮されたJSONLとしてダウンロードでき、1行に1ドメインずつ、そのままどのデータベースやスクリプトにも読み込める形式です。まったく同じリストはAPI経由でも取得できます。

.ac.jpドメインだけをダウンロードできますか、それともデータベース全体もダウンロードできますか？

両方とも可能です。各データセットは単体でダウンロードできる1つのファイルなので、.ac.jpに必要な分だけ購入できます。またはAll dataを購入すれば、データベース全体、つまりすべてのデータセット（識別情報、ランキング、技術、DNS、RDAP/WHOIS）を結合した1ファイルを入手できます。毎日新しくエクスポートされます。
