Configuring dynamic domain name resolution
To send DNS queries to a correct server for resolution, dynamic domain name resolution needs to be
enabled and a DNS server needs to be configured.
In addition, you can configure a DNS suffix that the system will automatically add to the provided
domain name for resolution.
To configure dynamic domain name resolution:

NOTE:
• You can configure up to six DNS servers, including those with IPv6 addresses, in system view and on all

• 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, i
t
is sent to the DNS server that has the second highest priority, and thus in turn.
• You can specify up to ten DNS suffixes.
