1. Setup the /etc/resolv.conf file with your DNS server name entries
2. Configure your /etc/nsswitch.conf file for the hosts entry to look up the dns server first,
eg:
hosts: dns nis [NOTFOUND=return] files

Hai,

hostname resolvation(s) are based on hosts: entry in the /etc/nsswitch.conf file.

IF you set hosts as,

hosts: dns files ldap nis

dns will be used in the begin to resolve the hostname. IF it is not succeeded files, then ldap and nis will be used.

To make ur hostname resolved using dns,
use the dns before files option.

dns will resolve hostname with /etc/resolv.conf and hosts will be using /etc/hosts file.

/etc/resolv.conf
domain domainname1.dom2.domn.com
nameserver
nameserver

It will resolve the hostnames using nameserver1 ... nameservern one by one,if it is not resolved.

Edit your /etc/nsswitch.conf file and add/change:

hosts: dns [NOTFOUND=continue] files

You also need to setup /etc/resolv.conf:

domain
nameserver
nameserver
