• 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.

• 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.
