Description
Admin Mode
The administrative mode of the DNS client.
Default Domain
The default domain name for the DNS client to use to complete
Name
unqualified host names. Domain names are typically composed of a
series of labels concatenated with dots. After a default domain name
is configured, if you enter a host name and do not include the domain
name information, the default domain name is automatically
appended to the host name.
Retry Number
The number of times the DNS client should attempt to send DNS que-
ries to a DNS server on the network.
Response Timeout
The number of seconds the DNS client should wait for a response to a
(secs)
DNS query.
Domain List
The list of domain names that have been added to the DNS client's
domain list. If a DNS query that includes the default domain name is
not resolved, the DNS client attempts to use the domain names in this
list to extend the hostname into a fully-qualified domain name. The
DNS client uses the entries in the order that they appear in the list.
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.

IPv6 addresses on the network, which are statically assigned to particular hosts.

Description
Entry Type
Type of DNS entry:
Host Name
The name that identifies the system. For Static entries, specify the
Host Name after you click Add. A host name can contain up to 255
characters if it contains multiple levels in the domain hierarchy, but
each level (the portion preceding a period) can contain a maximum of
63 characters. If the host name you specify is a single level (does not
contain any periods), the maximum number of allowed characters is
63.
Static: An entry that has been manually configured on the
device.
Dynamic: An entry that the device has learned by using a config-
ured DNS server to resolve a hostname.
