How to Flush DNS in IE

When you access a website via Internet Explorer, the browser first connects to your domain name system server, which can often be provided by your ISP. The DNS server converts a website’s human-readable name (for example, “”) to a numerical IP address.

For faster retrieval, these DNS records are cached in a systemwide DNS cache. In rare cases, incorrect DNS entries might be kept, causing difficulties in connecting websites. To clear the systemwide DNS cache that Internet Explorer uses, use the “ipconfig” command.
