ドメイン別ホスト設置位置の特定

e-Societyで収集した約4800万のホストを対象に，IP−経度・緯度変換テーブルを用いて，すべてのホストの設置場所の特定を行いました．
全世界を，経度2°，緯度2°四方のグリッドに分割し，各グリッドにいくつのホストが存在していたかを計算しました．
ここでは，TLD毎にホストの分布情報を示したグラフ（PDFファイル）を掲載しております．


凡例
Total当該TLDに属するすべてのホスト数
Unknownホスト名でnslookupをかけて，IPが返ってこなかったホスト数
Inside当該TLDの国内に設置されていたホスト数
Outside当該TLDの国内には設置されていなかったホスト数
