Command Reference Guide – DNS Chapter 1 DNS Configuration Commands
1-7
Description
Use the ip host command to add a hostname-to-IP address mapping entry in the
static DNS list.
Use the undo ip host command to remove a mapping entry from the static DNS list.
By default, there is no entry in the static DNS list.
As one hostname can mapped to only one IP address, when you add multiple
hostname-to-address mapping entries with the same hostname, only the last one will
be valid.
Related command: display ip host.
Example
# Configure a mapping entry from the host named aaa to the IP address 10.110.0.1
<3Com> system-view
System View: return to User View with Ctrl+Z.
[3Com] ip host aaa 10.110.0.1
