DELL CONFIDENTIAL – PRELIMINARY 5/15/12 – FOR PROOF ONLY
Examples
The following example enables IP Domain Naming System (DNS)-based host name-to-address
translation.
ip domain-name
The ip domain-name Global Configuration mode command defines a default domain name used
by the software to complete unqualified host names (names without a dotted-decimal domain
name). Use the no form of this command to remove the default domain name.
Syntax
• ip domain-name name
• no ip domain-name
• name — Specifies the default domain name used to complete unqualified host names. Do not
include the initial period that separates an unqualified name from the domain name. (Range:
1 - 158 characters)
Default Configuration
A default domain name is not defined.
Command Mode
Global Configuration mode.
User Guidelines
• This command enables host name-to-address translation. The preference in name-to-address
resolution is determined by the type of host name-to-address entry. Static entries are read first,
followed by DHCP entries and DNS-protocol entries.
Examples
The following example defines default domain name dell.com.
ip name-server
The ip name-server Global Configuration mode command defines the available name servers. Use
the no form of this command to remove a name server.
Console(config)# ip domain-lookup
Console(config)# ip domain-name dell.com
