Configuring Dynamic Domain Name Resolution; Setting The Dscp Value For Dns Packets - HP 10500 Series Configuration Manual

Configuring dynamic domain name resolution

To send DNS queries to a correct server for resolution, enable dynamic domain name resolution and
configure a DNS server.
In addition, you can configure a DNS suffix that the system automatically adds to the provided domain
name for resolution.
Configuration guidelines
Follow these guidelines when you configure dynamic domain name resolution:
You can configure up to six DNS servers, including those with IPv6 addresses, in system view, and
•
up to six DNS servers on all interfaces of a device.
A DNS server configured in system view has a higher priority than one configured in interface view.
•
A DNS server configured earlier has a higher priority than one configured later in the same view.
A DNS server manually configured has a higher priority than one dynamically obtained through
DHCP. A name query request is first sent to the DNS server that has the highest priority. If no reply
is received, it is sent to the DNS server that has the second highest priority, and thus in turn.
You can specify up to ten DNS suffixes.
