Lista de endereços IP: 21.0.*.* (21.0.0.* - 21.0.255.*) | Endereço de IP (Português, Internacional) 🔍

You are here

Esta é a lista de endereços IP em que o primeiro byte é 21, o segundo byte é 0, o terceiro byte está entre 0 e 255, o quarto byte pode ser alterado (o asterisco abaixo) List, expresso como 21.0.*.* (21.0.0.0 - 21.0.255.255).

Esta lista de endereços IP contém 256 * 256 = 65.536 endereços IP. Vamos usar um dos endereços IP 21.0.1.1 como exemplo para descrever as propriedades deste IP:

Exemplo de primeiro endereço IP

Mas este é apenas um exemplo de um dos endereços IP. Isso não significa que todos os endereços IP nesta lista têm as mesmas propriedades. Se você precisar conhecer outros IPs e informações mais detalhadas sobre o endereço IP, clique no link do título.

2. Lista de endereços IP classe A

O endereço IP da classe A significa: no número de quatro partes do endereço IP (por exemplo: byte 1.byte 2.byte 3.byte 4), o primeiro número da peça (byte 1) é o número da rede, as três partes restantes números (byte 2.byte 3.byte 4) são o número do computador local.

Se o endereço IP for expresso em binário, o endereço IP da classe A consistirá em um endereço de rede de 1 byte e um endereço de host de 3 bytes, e o bit mais alto do endereço de rede deverá ser '0'.

Intervalo de endereços IP de classe A: 1.0.0.0 ~ 127.255.255.255, intervalo de endereços IP disponível: 1.0.0.1 ~ 127.255.255.254.

O comprimento do identificador de rede no endereço IP da classe A é de 7 bits, e o comprimento do identificador de host é de 24 bits. O número de endereços de rede da classe A é relativamente pequeno (2 ^ 7 - 2 = 126), que pode ser usado para mais de 160 milhões de hosts de redes grandes (2 ^ 24 - 2 = 16.777.214).
