**Table 1** Description of the **display dns configuration** command output
Item	Description
Dns resolve	Whether dynamic DNS resolution is enabled. The value can be: Enabled: Dynamic DNS resolution is enabled. Disabled: Dynamic DNS resolution is disabled. To enable dynamic DNS resolution, run the dns resolve command.
DNS-server-select-algorithm	Algorithm for selecting a destination DNS server. The value can be: Fixed: The destination DNS server is selected in fixed order. Auto: The destination DNS server is selected in auto order. To specify an algorithm for selecting a destination DNS server, run the dns-server-select-algorithm command.
Dns server source ip address	Source IP address of the local device for communication. To set the source IP address of the local device, run the dns server source-ip command.
Dns server source ipv6 address	Source IPv6 address of the local device for communication. To set the source IPv6 address of the local device, run the dns server ipv6 source-ip command.
Dns server source interface	Whether the IP address of a specified interface is used as the source IP address for DNS communication on the local device. To set the IP address of a specified interface as the source IP address, run the dns server source-interface command.
Dns proxy	Whether DNS proxy is enabled. The value can be: Enabled: DNS proxy is enabled. Disabled: DNS proxy is disabled. To enable DNS proxy, run the dns proxy enable command.
Dns IPv6 proxy	Whether IPv6 DNS proxy is enabled. The value can be: Enabled: IPv6 DNS proxy is enabled. Disabled: IPv6 DNS proxy is disabled. To enable IPv6 DNS proxy, run the dns proxy ipv6 enable command.
Dns relay	Whether DNS relay is enabled. The value can be: Enabled: DNS relay is enabled. Disabled: DNS relay is disabled. To enable DNS relay, run the dns relay enable command.
Dns IPv6 relay	Whether IPv6 DNS relay is enabled. The value can be: Enabled: IPv6 DNS relay is enabled. Disabled: IPv6 DNS relay is disabled. To enable IPv6 DNS relay, run the dns relay ipv6 enable command.
Dns forward retry-number	Number of times for retransmitting query messages to the destination DNS server. To set the number of times for retransmitting query messages to the destination DNS server, run the dns forward retry-number command.
Dns forward retry-timeout	Retransmission timeout period that the device sends query messages to the destination DNS server. To set the retransmission timeout period that the device sends query messages to the destination DNS server, run the dns forward retry-timeout command.
Dns application cache ttl limit	Limited TTL of the Cache of application domain name resolution. This parameter can be configured using the command dns application cache ttl.
Dns server unnumbered interface	IPv4 address of the DNS server obtained through a specified interface. To configure this item, run the dns server unnumbered command.
Dns server ipv6 unnumbered interface	IPv6 address of the DNS server obtained through a specified interface. In the item: dhcpv6: Obtains the IPv6 address of the DNS server from DHCPv6 information of the specified interface. nd-ra: Obtains the IPv6 address of the DNS server from ND information of the specified interface. To configure this item, run the dns server ipv6 unnumbered command.
