Name
ip domain-lookup — global
Synopsis
ip domain-lookup no ip domain-lookup
Configures
DNS lookups for hostnames
Default
Enabled
Description
This command enables the DNS lookup feature. To disable DNS, use the no form of this command. Disabling this feature is useful because you don’t usually want the router trying to perform a DNS lookup on every word that you type at the command prompt. (You can accomplish the same thing by enabling transport preferred none on all lines.) Furthermore, if you are having network problems, you may not be able to reach any DNS servers to perform lookups.
Example
To disable DNS lookups:
no ip domain-lookup
