Explanation

DNS provides hostname-to-IP resolution. A cache stores recently learned mappings to reduce lookup time. A name resolver is the client-side component that sends queries to DNS servers on behalf of applications. A domain identifies an administrative or organizational portion of an Internet name, including top-level categories such as .com or country domains. On Cisco IOS, no ip domain-lookup disables DNS lookup behavior.
