CLUBE

clipped from www.guiadohardware.net Normalmente, para registrar um domínio é necessário ter um servidor com dois IPs fixos (ou dois servidores, com um IP cada), de forma a configurar os dois servidores DNS necessários. Os servidores do registro.br ou da entidade responsável pelo seu domínio passam então a redirecionar as requisições para o seu servidor DNS primário, que responde com o endereço IP do servidor. Um exemplo de configuração para um servidor DNS rodando o Bind seria: @ IN SOA servidor.gdhn.com.br. hostmaster.gdhn.com.br. ( 2008040645 3H 15M 1W 1D ) NS servidor.gdhn.com.br. IN MX 10 servidor.gdhn.com.br. gdhn.com.br. A 64.234.23.12 www A 64.234.23.12 ftp A 64.234.23.12 Como você pode ver, as três últimas linhas do arquivo relacionam o domínio e mais dois subdomínios com o endereço IP do servidor, de forma que ao acessar os endereços “gdhn.com.br” “www.gdhn.com.br” ou “ftp.gdhn.com.br” o cliente seria encaminhado para o endereço “64.234.23.12″, que é o endereço IP do servidor no exemplo.
