Igor,

Esta interface que vc está utilizando, testa somente a autoridade do
servidor para uma zona. www.nasa.gov não é uma zona, somente um CNAME
para a rede de distribuição de conteúdo do site da nasa. Teste
novamente para o domínio nasa.gov. A resposta deverá ser correta.

Domínio nasa.gov
DNS 198.116.144.33
  Autoridade sobre o domínio
   2004021702
  Tempo de resposta -> 0.22 s

Da rede do registro.br, aparentemente, não existe restrição
alguma.
