• Default Parameters—Enter the following default parameters:
- Default Domain Name—Enter the DNS domain name used to complete unqualified
host names. The device appends this to all non-fully qualified domain names
(NFQDNs) turning them into FQDNs.
NOTE Do not include the initial period that separates an unqualified name from the
domain name (like cisco.com).
- DHCP Domain Search List—Click Details to view the list of DNS servers
configured on the device.
STEP 4 Click Apply. The Running Configuration file is updated.
The DNS Server Table displays the following information for each DNS server configured:
• DNS Server—The IP address of the DNS server.
• Preference—Each server has a preference value, a lower value means a higher chance
of being used.
• Source—Source of the server’s IP address (static or DHCPv4 or DHCPv6)
• Interface—Interface of the server’s IP address.
STEP 5 Up to eight DNS servers can be defined. To add a DNS server, click Add.
STEP 6 Enter the parameters.
• IP Version—Select Version 6 for IPv6 or Version 4 for IPv4.
• IPv6 Address Type—Select the IPv6 address type (if IPv6 is used). The options are:
- Link Local—The IPv6 address uniquely identifies hosts on a single network link. A
link local address has a prefix of FE80, is not routable, and can be used for
communication only on the local network. Only one link local address is supported.
If a link local address exists on the interface, this entry replaces the address in the
configuration.
- Global—The IPv6 address is a global Unicast IPV6 type that is visible and
reachable from other networks.
• Link Local Interface—If the IPv6 address type is Link Local, select the interface
through which it is received.
• DNS Server IP Address—Enter the DNS server IP address.
• Preference—Select a value that determines the order in which the domains are used
(from low to high). This effectively determines the order in which unqualified names
are completed during DNS queries.
