Hola foro, tengo el siguiente problema; configuré un dns basandome en los manuales del sitio www.linuxparatodos.net; si me resuelve de forma externa, pero de forma interna (ips locales y hostnames) no me resuelve.

ejecuto el siguiente comando:

nslookup huitzilinmx01 localhost

y me contesta...

;; connection timed out; no servers could be reached

caso contrario si ejecuto el comando:

nslookup www.bancomer.com 172.16.46.3

me contesta....

Server: 172.16.46.3
Address: 172.16.46.3#53

Non-authoritative answer:
Name: www.bancomer.com
Address: 148.244.43.5

me podrían ayudar a localizar el error y a solucionarlo,
gracias.
