If you are choosing any of the options for using DNS, follow these steps:

* Set the **nameservers** and **forwarders** attributes in the xCAT site table. The **nameservers** attribute identifies the DNS server hostname/ip that the nodes point to in their **/etc/resolv.conf** files. The forwarders attribute are the DNS server's ip that can resolve external hostnames. If you are running a DNS on the xCAT MN, it will use the forwarders DNS server to resolve any hostnames it can't.
