This configuration applies to both IPv4 DNS and IPv6 DNS.
You can configure a maximum of 128 DNS trusted interfaces on the device.
If you do not specify an interface, the
undo dns trust-interface
command removes all DNS
trusted interfaces and restores the default.
Examples
# Specify VLAN-interface 2 as a DNS trusted interface.
<Sysname> system-view
[Sysname] dns trust-interface vlan-interface 2
ip host
Use ip host to create a host name-to-IPv4 address mapping.
Use undo ip host to remove a host name-to-IPv4 address mapping.
Syntax
ip host host-name ip-address [ vpn-instance vpn-instance-name ]
undo ip host host-name ip-address [ vpn-instance vpn-instance-name ]
Default
No host name-to-IPv4 address mappings exist.

Parameters
host-name:
Specifies a host name, a case-insensitive string of 1 to 253 characters. Valid
characters are letters, digits, hyphens (-), underscores (_), and dots (.).
ip-address
: Specifies the IPv4 address of the host.
vpn-instance vpn-instance-name
: Specifies an MPLS L3VPN instance by its name, a
case-sensitive string of 1 to 31 characters. To create a host name-to-IP address mapping for the
public network, do not specify this option.
Usage guidelines
The system allows a maximum of 1024 host name-to-IPv4 address mappings for the public network
or each VPN instance. You can configure host name-to-IPv4 address mappings for both public
network and VPN instances.
For the public network or a VPN instance, each host name maps to only one IPv4 address. If you
execute this command multiple times, the most recent configuration takes effect.
