adds a terminating period and then queries DNS using 
that name.
However, if you enter a single-label, unqualified 
name, or a multiple-label, unqualified name, and the 
name fails to resolve as an FQDN, the resolver 
systematically appends different DNS suffixes to the 
name that you entered, adding periods to make them 
FQDNs. The resolver then resubmits the name to DNS.
If you have not entered a domain suffix search list, the 
DNS resolver appends the following names: 
1. The primary DNS suffix. 
2. If the DNS suffix does not successfully resolve 
after you enter the DNS name, the resolver 
appends each connection-specific DNS suffix. 
This suffix can be dynamically assigned by the 
DHCP server. You can also specify suffixes on the 
DNS
 tab in the 
Global Network Settings
From the primary menu bar, select 
Network 
Setup
, then click 
Global Network Settings
If DNS name resolution is still unsuccessful, the DNS 
resolver devolves the FQDN by appending the parent 
suffix of the primary DNS suffix name, and the parent 
of that suffix, and so on, until only two labels are left
On the other hand, if you have entered a list of specific 
DNS suffixes, both the primary DNS suffix and the 
connection-specific domain name are ignored. In such 
a case, neither is appended to the host name before 
the FQDN are submitted to DNS. Instead, the resolver 
appends each suffix from the search list in order, and 
then submits the name to the DNS server until the 
resolver finds a match or reaches the end of the list. 
For example, if you enter the name client, and the 
primary DNS suffix is eu.reskit.com, the resolver will 
first try client.eu.reskit.com, and then 
client.reskit.com.
