CIDRをIPアドレスに展開ツール v2.0.3
IPv4形式のIPアドレスは192.168.0.1などの一般的な形式だけでなく、
192.168.0.1/24 などのネットマスク指定(/24部分)による範囲指定なども利用ができます。
これはCIDR形式、プレフィックス指定などとも呼ばれています。
ここではこのネットマスク指定によるIPアドレス範囲をIPアドレスに展開して表示します。
以下に、ネットマスク形式のIPアドレスを入力すると、
下部に対して、CIDR指定に含まれるIPアドレスが表示されます。
また範囲が広く、含まれるIPアドレスが多い場合には、
結果は「xxx.xxx.xxx.xxx – xxx.xxx.xxx.xxx」形式の範囲で表示します。
範囲表示された場合は、リンクをクリックすると範囲内のIPを再展開できます。

CIDR形式 (62.216.106.0/23) から範囲内のIPアドレス展開
表示値でそのまま実行するとデモ動作の確認ができます。

このツールに関連してCIDRをすべて展開するのではなく、
CIDR範囲に1つのIPアドレスが含まれているかどうかを、
チェックして確認するツールを作成公開しました。
併せてご活用いただければ幸いです。
さいごに
CIDRからIPアドレスの範囲をイメージすることは、
慣れるまでは少しとっつきにくい部分もあります。
ここでは実際に範囲を目視して、
それぞれの範囲を細かく見ていくことができるようにしています。
お役に立ちますと幸いです。
