2つのIPアドレス範囲をCIDR化とIPアドレス展開ツール(スーパーネット化) v2.0.1
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による範囲指定なども利用ができます。
プロバイダなどから提供される情報が2つのIPアドレス範囲の場合に、
2つのIPアドレスからCIDRネットマスク形式(192.168.0.1/24)を求めて表示します。
以下に、2つのIPアドレスを入力すると、
条件を満たすCIDRネットマスク形式が表示されます。
さらに、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。

IPアドレスの特殊属性
入力されたIPアドレス範囲の特殊IP属性に関する情報です。
特殊属性には該当しませんでした。
IP特殊属性 | 概要 | CIDR |

IPアドレスの特殊属性に割当てられた
各範囲・グローバルIPアドレスの範囲については、
以下リンク先でご確認下さい。
(注意事項)
このツールが2つのIPアドレスから表示するCIDR(ネットマスク形式)は、
2つのIPアドレスが含まれるネットワーク帯域全体のIPアドレスを求めます。
例) 「192.168.0.1 ~ 192.168.0.250」とした場合には、
192.168.0.0/24(192.168.0.0~192.168.0.255)を表示します。
※192.168.0.251~192.168.0.255は指定していない範囲のIPアドレス
その為、範囲外のIPアドレスが一部含まれる可能性があります。
これはあくまでも、同一ネットワーク帯のIP範囲を求めることを目的にしています。
一般的に言えば、この2つのIPアドレスが連続していると想定し、
「スーパーネットワーク化」を行うイメージです。
このツールの使用方法については以下でご紹介しています。

2015/02/27追記
新機能を公開しました。
もし、こうしたスーパーネット化によるCIDRではなく、
2つのIPアドレスの範囲を厳密にCIDRで表現がしたい場合には、
以下のツールを利用することで、
無用な範囲を含まないようにCIDR化することができます。
