Figure 41 Adding a mapping between domain name and IP address
2. Configure the DNS client:
# Specify the DNS server 2.1.1.2.
<Sysname> system-view
[Sysname] dns server 2.1.1.2
# Specify com as the name suffix.
[Sysname] dns domain com
Verifying the configuration
# Verify that the device can use the dynamic domain name resolution to resolve domain name
host.com into IP address 3.1.1.1.
[Sysname] ping host
Ping host.com (3.1.1.1): 56 data bytes, press CTRL_C to break
56 bytes from 3.1.1.1: icmp_seq=0 ttl=255 time=1.000 ms
56 bytes from 3.1.1.1: icmp_seq=1 ttl=255 time=1.000 ms
56 bytes from 3.1.1.1: icmp_seq=2 ttl=255 time=1.000 ms
56 bytes from 3.1.1.1: icmp_seq=3 ttl=255 time=1.000 ms
56 bytes from 3.1.1.1: icmp_seq=4 ttl=255 time=2.000 ms
--- Ping statistics for host ---
5 packet(s) transmitted, 5 packet(s) received, 0.0% packet loss
round-trip min/avg/max/std-dev = 1.000/1.200/2.000/0.400 ms
Example: Configuring DNS proxy
Network configuration
As shown in Figure 42, configure Device A as the DNS proxy to forward DNS packets between the
DNS client (Device B) and the DNS server at 4.1.1.1.
