Elenco di indirizzi IP: 21.91.*.* (21.91.0.* - 21.91.255.*) | Indirizzo IP (Italiano) 🔍

Tu sei qui

Questo è l'elenco di indirizzi IP in cui il primo byte è 21, il secondo byte è 91, il terzo byte è compreso tra 0 e 255, il quarto byte può essere modificato (l'asterisco in basso) Elenco, espresso come 21.91.*.* (21.91.0.0 - 21.91.255.255).

Questo elenco di indirizzi IP contiene 256 * 256 = 65.536 indirizzi IP. Prendiamo uno degli indirizzi IP 21.91.1.1 come esempio per descrivere le proprietà di questo IP:

Esempio di primo indirizzo IP

Ma questo è solo un esempio di uno degli indirizzi IP. Ciò non significa che tutti gli indirizzi IP in questo elenco abbiano le stesse proprietà. Se hai bisogno di conoscere altri IP e informazioni più dettagliate sull'indirizzo IP, fai clic sul link del titolo.

2. Elenco di indirizzi IP di classe A

Indirizzo IP di classe A significa: nel numero in quattro parti dell'indirizzo IP (ad esempio: byte 1.byte 2.byte 3.byte 4), il primo numero di parte (byte 1) è il numero di rete, le restanti tre parti i numeri (byte 2.byte 3.byte 4) sono i numeri del computer locale.

Se l'indirizzo IP è espresso in binario, l'indirizzo IP di classe A è costituito da un indirizzo di rete a 1 byte e da un indirizzo host a 3 byte e il bit più alto dell'indirizzo di rete deve essere '0'.

Intervallo di indirizzi IP di classe A: 1.0.0.0 ~ 127.255.255.255, intervallo di indirizzi IP disponibile: 1.0.0.1 ~ 127.255.255.254.

La lunghezza dell'identificatore di rete nell'indirizzo IP di classe A è 7 bit e la lunghezza dell'identificatore host è 24 bit. Il numero di indirizzi di rete di classe A è relativamente piccolo (2 ^ 7 - 2 = 126), che può essere utilizzato per oltre 160 milioni di host di reti di grandi dimensioni (2 ^ 24 - 2 = 16.777.214).
