IPアドレスのリスト: 21.142.*.* (21.142.0.* - 21.142.255.*)

現在地

これは、最初のバイトが21、2番目のバイトが142、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 21.142.*.*（21.142.0.0 - 21.142.255.255）。

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21.142.1.1の1つを取り上げます。

最初のIPアドレスの例

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。
