Acerca de .arpa
.arpa é uma das extensões de domínio mais antigas e tecnicamente mais importantes da internet, criada originalmente como parte da infraestrutura ARPANET em 1985. Gerida exclusivamente pela IANA (Internet Assigned Numbers Authority) em nome do Internet Architecture Board (IAB), a .arpa é uma extensão de infraestrutura não disponível para registo público. O seu uso principal destina-se a funções técnicas da internet, incluindo pesquisas de DNS inverso (in-addr.arpa para IPv4 e ip6.arpa para IPv6), que permitem associar endereços IP a nomes de domínio.
O nome da extensão .arpa deriva da Advanced Research Projects Agency (ARPA), a agência governamental dos Estados Unidos que financiou o desenvolvimento do precursor da internet. Atualmente, a .arpa sustenta funções críticas de encaminhamento e endereçamento na internet, e os seus subdomínios são essenciais para o funcionamento correto do correio eletrónico, da navegação na web e do diagnóstico de redes. Apesar do seu baixo perfil público, a .arpa é uma das extensões mais consultadas no sistema DNS, uma vez que as pesquisas de DNS inverso ocorrem constantemente em toda a infraestrutura global da internet.

Uma amostra gratuita da lista está disponível antes de pagar, e pode voltar a transferir o export mais recente a qualquer momento durante o seu mês de acesso.
Cada lista de .arpa inclui, para cada domínio:
- Registos DNS, RDAP e WHOIS, registrar e datas em toda a lista.
- Tecnologias detetadas para cada site da lista.
- IP de alojamento, país e ranking PageRank / Harmonic.
- Uma exportação atualizada diariamente, para que a lista que recebe nunca esteja desatualizada.
