The DNS cache is a record of domain names converted into IP addresses during Web browsing and similar activities. The cache makes accessing these IP addresses faster by remembering the IP instead of having to look it up based on the entered domain. Despite the number of addresses the cache can amass over time, flushing the cache isn’t always necessary. There are, however, circumstances where it may be a wise decision. Enter the following command in this folder: net stop dnscache This stops DNS caching for this session. To restart DNS caching for this session, enter the following command: net start dnscache
