IPアドレスのリスト: 21.103.*.* (21.103.0.* - 21.103.255.*)

現在地

これは、最初のバイトが21、2番目のバイトが103、3番目のバイトが0〜255のIPアドレスのリストです。4番目のバイトは変更できます（以下のアスタリスク）。として表されます 21.103.*.*（21.103.0.0 - 21.103.255.255）。

このIPアドレスリストには、256 * 256 = 65,536のIPアドレスが含まれています。このIPのプロパティを説明する例として、IPアドレス21.103.1.1の1つを取り上げます。

最初のIPアドレスの例

ただし、これはIPアドレスの1つの例にすぎません。このリストのすべてのIPアドレスが同じプロパティを持つことを意味するものではありません。他のIPとより詳細なIPアドレス情報を知る必要がある場合は、タイトルリンクをクリックしてください。

2. クラスAIPアドレスのリスト

クラスAのIPアドレスとは、IPアドレスの4部構成の番号（たとえば、バイト1.バイト2.バイト3.バイト4）で、最初のパート番号（バイト1）がネットワーク番号、残りの3つが数値（バイト2.バイト3.バイト4）は、ローカルコンピューターの番号です。

IPアドレスがバイナリで表現されている場合、クラスAのIPアドレスは1バイトのネットワークアドレスと3バイトのホストアドレスで構成され、ネットワークアドレスの最上位ビットは「0」でなければなりません。

クラスA IPアドレス範囲：1.0.0.0 ~ 127.255.255.255、使用可能なIPアドレス範囲：1.0.0.1 ~ 127.255.255.254。

クラスA IPアドレスのネットワークIDの長さは7ビットで、ホストIDの長さは24ビットです。クラスAネットワークアドレスの数は比較的少なく（2 ^ 7 - 2 = 126）、大規模ネットワークの1億6千万を超えるホスト（2 ^ 24 - 2 = 16,777,214）に使用できます。
