When you type a web address into your web browser and press ENTER, you are sending a query to a DNS server. If the query is successful, the website you want opens; if not, you'll see an error message. A record of these successful and unsuccessful queries is stored in a temporary storage location on your computer called the DNS cache. DNS always checks the cache before querying any DNS server, and if a record is found that matches the query, DNS uses that record instead of querying the server. This makes queries faster and decreases network and Internet traffic.
Clearing the DNS cache to discard negative cache entries from the cache, as well as any other dynamically added entries, forces DNS to query a DNS server rather than using information stored in the cache. You might want to clear the DNS cache if you are moving and changing websites, or if you are receiving repeated errors when you know the web address you are typing is correct.
