1267BNetwork requirements
As shown in 2451HFigure 142, the firewall 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 firewall so that the firewall can use the domain name
host.com to access the host whose IP address is 10.1.1.2.

1268BConfiguration procedure
# Configure a mapping between host name host.com and IP address 10.1.1.2.
<Firewall> system-view
[Firewall] ip host host.com 10.1.1.2
# Use the ping host.com command to verify that the firewall can use static domain name resolution to
resolve domain name host.com into IP address 10.1.1.2.
[Firewall] ping host.com
