NOTE: CentOS Enterprise Linux is built from the Red Hat Enterprise Linux source code. Other than logo and name changes CentOS Enterprise Linux is compatible with the equivalent Red Hat version. This document applies equally to both Red Hat and CentOS Enterprise Linux.

18.8. Managing DNS Settings

The DNS tab allows you to configure the system's hostname, domain, name servers, and search domain. Name servers are used to look up other hosts on the network.

If the DNS server names are retrieved from DHCP or PPPoE (or retrieved from the ISP), do not add primary, secondary, or tertiary DNS servers.

If the hostname is retrieved dynamically from DHCP or PPPoE (or retrieved from the ISP), do not change it.

Figure 18-14. DNS Configuration

Note Note
 

The name servers section does not configure the system to be a name server. Instead, it configures the name servers to use when resolving IP addresses to hostnames and vice versa.
