Answer:
No ip dns server.
Explanation:
The DNS stands for domain name services. It can be statically or dynamically configured to a workstation from the DHCP request. It resolves the ip address of a server to it's name, so a client is not burdened by memorizing the ip address of every website.
In the cisco ios, the "NO" command is used to negate other commands, so when a "no ip dns server" is used configured on a device, it stops every website name lookups.
