In some systems, a Domain Suffix Search Order capability is provided. The Domain Suffix Search Order specifies the DNS domain suffixes to be
appended to the host names during name resolution. When attempting to resolve a fully qualified domain name (FQDN) from a host only name, the system will first append the local domain name. If this is not successful, the system will use the Domain Suffix list to create additional FQDNs in the order listed and query DNS servers for each.
An example client configuration from a machine running Windows NT 4.0 is illustrated below.
