Existe uma diferença entre uma pesquisa de servidor de nomes e uma pesquisa de nome de domínio?
Uma pesquisa de servidor de nomes recupera o endereço IP associado a um nome de domínio.
Uma pesquisa de nome de domínio (também chamada de whois
) recupera os dados de registro de domínio (os detalhes do proprietário do domínio).
Como faço uma pesquisa no servidor de nomes?
-
On-line usando uma variedade de serviços de pesquisa de servidor de nomes
-
No Windows, use o nslookup
-
No Unix, use dig .
