When Internet Explorer connects to a Web server and the IP address list returned from the DNS servers contains multiple IP addresses, Internet Explorer tries to make a TCP connection using these IP addresses in the order in which they were received. Once a TCP connection is successfully established, Internet Explorer uses that IP address to send the HTTP request to.
However, by default Internet Explorer only attempts to use the first five IP addresses it receives from DNS when it tries to establish a TCP connection. If it fails to make a connection to all five IP addresses, the problem outlined in the Symptoms section can occur.
