Primeiro precisamos de um arquivo chamado geoIP.dat que contém as informações necessárias para interagir com os scripts php que irei propor abaixo. Como eu não tenho opção de anexar arquivos por aqui, irei disponibilizar o arquivo em meu domínio.
Não é um caminho simples para que se possa identificar corretamente o PAÍS do visitante que acessa sua página, por isso o script e o arquivo DAT são necessários pois contém informações especiais sobre DNS's e IP's Nacionais e internacionais, para que possam ser comparados com os de cada visitante que nos acessa.
Feito isso, vamos agora criar uma página intitulada "geoip.inc"
geoip.inc
