Parameters 
hostname: Host name, a string of 1 to 20 characters which can be letters, numbers, hyphens (-), or dots 
(.). The host name must include at least one letter. 
ip-address: IP address of the specified host, in dotted decimal notation. 
Description 
Use the ip host command to create a mapping between host name and IP address in the static DNS 
database. 
Use the undo ip host command to remove the mapping. 
No mappings are created by default. 
Each host name can correspond to only one IP address. When IP addresses are configured for the 
same host for multiple times, only the IP address configured last time is valid.
