Default Domain
Name
The default domain name (255 characters maximum) that the DNS client uses to complete unqualified host
names. After a default domain name is configured (default: not configured), a host name entered without
domain name information is appended with the default domain name. For example, if the default domain name
is
.com
and the user enters
hotmail
as the host name, then the host name is changed to
hotmail.com
.
Retry Number
The number of times to resend DNS queries to a DNS server on the network. Range is
0
to
100
. The default is
2
.
Response Timeout
The number of seconds to allow a DNS server to respond to a request before a retry. Range is
0
to
3600
. Default is
3
.
Domain List
The domain names that have added to the DNS client’s domain list. If a DNS query that includes the default
domain name is not resolved, the DNS client uses these domain names, in the order they appear in this list, to
extend the hostname into a fully-qualified domain name. Use the buttons as follows:
To create a new list of domain names, click this button, enter the name of the list, and click
Submit
.
Repeat this step to add multiple domains to the default domain list.
To remove a domain from the domain list, click this button and then confirm the action.
DNS Server
A unique IPv4 or IPv6 address used to identify a DNS server. The order in which you add servers determines the
precedence of the server. The DNS server that you add first has the highest precedence and will be used before
other DNS servers that you add. Use the buttons as follows:
