host dns lookup curiosidade

2

Alguém pode me ajudar a entender isso: -

%)-- host brahma.mksh.net      
Host brahma.mksh.net not found: 3(NXDOMAIN)

agora, quando eu executo dig com trace .. Eu recebo o registro A para brahma.mksh.net que eu atribuí ..

%)-- dig brahma.mksh.net +trace

; <<>> DiG 9.3.6-P1-RedHat-9.3.6-4.P1.el5 <<>> brahma.mksh.net +trace

O nome está resolvendo bem. Algo está em cache no DNS do seu host ou no seu resolvedor, o que dá a você NXDOMAIN - dê um tempo, mas está funcionando bem nos servidores DNS do Google.
