IPV4 network calculation project in Python

Curso de Python 3 do Básico ao Avançado

Desafio: Calculando redes IPV4

Criar um programa que obtem um numero de IP com o prefixo da mascara de rede.

O sistema irá calcular:

  • O IP da mascara de Rede
  • Primeiro IP
  • Ultimo IP
  • Total de hosts
  • IP e Mascara de rede convertidos em Binários

Solução:

Abaixo as funções vão receber a entrada de informção, a função validanumero tira os "." e '/" tornando uma lista com 5 itens, verificando se cada item não passa de 3 caracteres.

A função numero_ip converte cada membro da lista gerada em numero inteiro e verifica se o prefixo da mascara é valido.

from valida_ip import validanumero, numero_ip

print('Digite um endereço IP e o prefixo da mascara de rede:')
ip = input()
numero_ip(validanumero(ip))
from ipv4 import IPV4

def validanumero(valor):
    valor = valor.replace('/','.')
    valor = valor.split('.')
    for i in valor:
        if len(i) > 3:
            return
    return valor

def numero_ip(funcao):
    try:
        grupo1 = int(funcao[0])
        grupo2 = int(funcao[1])
        grupo3 = int(funcao[2])
        grupo4 = int(funcao[3])
        masc = int(funcao[4])

        if not masc <=32 or not masc >= 24:
            return print('Prefixo de máscara inválido')

        ipv4 = IPV4(grupo1, grupo2, grupo3, grupo4, masc)
        ipv4.lista_de_ip()
    except:
        print('Número de ip invalido')

Após a validação do numero IP é passado pelas funções converter_para_binario e binario_mascara_de_rede para a conversão do IP e mascara de rede em binário.
A função ip_mascara_de_rede gera uma nova mascara de rede e numerodehost gera o numero de Host que pode setar IP.

CALCULAR = [128, 64, 32, 16, 8, 4, 2, 1]

                f'# PRIMEIRO IP: {self.grupo1}.{self.grupo2}.{self.grupo3}.1/{self.mascarasubrede}\n'
                f'# ÚLTIMO IP: {self.grupo1}.{self.grupo2}.{self.grupo3}.{self.numerodehost()}/{self.mascarasubrede}\n'
                f'# Nº DE IPs: {self.numerodehost()}')
            print('#' * 56)
            print(f'# Números em binários: \n'
                  f'# IP: {ip1}.{ip2}.{ip3}.{ip4}\n'
                  f'# Mascara de rede: 11111111.11111111.11111111.{masc}')
        else:
            print('Número de ip invalido')
