Static domain name resolution configuration example
Network requirements
As shown in Figure 37 , the device wants to access the host by using an easy-to-remember domain name
rather than an IP address.
Configure static domain name resolution on the device so that the device can use the domain name
host.com to access the host whose IP address is 10.1.1.2.
Figure 37 Network diagram for static domain name resolution
Configuration procedure
# Configure a mapping between host name host.com and IP address 10.1.1.2.
system-view
[Sysname] ip host host.com 10.1.1.2
# Use the ping host.com command to verify that the device can use static domain name resolution to
resolve domain name host.com into IP address 10.1.1.2.
[Sysname] ping host.com
