Eu percebi que no Mac a exibição dessas informações de rede são um tanto confusa, inclusive, fiquei com algumas dúvidas. Por exemplo, na minha máquina foram exibidas as seguintes infos com o comando ifconfig, e os campos que correspondem ao IP da minha máquina é 192.168.1.3, e a máscara de rede é 0xffffff00 que é o correspondente a 255.255.255.0, mas a info correspondente ao gateway eu não achei com o ifconfig, só consegui acessando as configurações de rede no system preferences, ai sim eu vi e consegui acessar a página do provedor usando o IP 192.168.1.254. Existe algum outro comando no Mac melhor que o ifconfig?
