Manage the Nameserver (DNS) Cache
As mentioned a few times elsewhere in this chapter, a nameserver (or DNS)
is a machine that translates IP addresses to domain names and back again.
For example, when you type http://www.oreilly.com into your web browser??™s
address bar, Windows sends a request to your service provider??™s nameserver,
and the nameserver responds with something like 209.204.146.22, and your
browser can contact the web server and download the requested page.
Each time such a DNS (Domain Naming System) lookup is performed, the
information is stored in the DNS cache so Windows doesn??™t have to query
the nameserver every time you access a page on that site. The DNS cache is
emptied when you shut down Windows, which is why it can take a little
longer to find web sites just after you??™ve booted up.
The following two solutions allow you to change the way Windows interacts
with its DNS cache, and will affect all applications that access the Internet
(not just your web browser).
