I have registered my nameserver  at registrar. I have properly updated the zone file in the server. But for some reason while checking the dig result the new name-server details were not showing correctly. I have checked the logs and got the following error. view external: query (cache) denied Reason : in the view external section in named.conf, the entry for my domain was commented. Once I un-comment, everything was correct. If you got similar type of error, check your named.conf and also check whether named.conf and the zone file is ok using the following commands named-checkconf named-checkzone domain.com /var/named/domain.com.db
