What is negative caching?

Rating:

When DNS resolves a hostname to an IP address, the hostname/IP address pair is stored in the cache on the host that originated the request. However, if the resolution is unsuccessful even if the host name is correct, that negative information is also cached. It is called negative caching. Administrators can resolve the problem of negative caching by using the IPCONFIG /flushdns command that purges the DNS cache.
