SYMPTOMS

When you connect to a Web server using the Internet Protocol (IP) address or Fully Qualified Domain Name (FQDN) on the local network, Microsoft Internet Explorer or Windows Internet Explorer connects through an assigned proxy server even if the Bypass proxy server for local addresses option is turned on.

However, if you connect to a Web server using the host name (for example, http://webserver) instead of the IP address (for example, http://10.0.0.1) or FQDN (for example, http://webserver.domainname.com), the proxy server is bypassed and Internet Explorer connects directly to the server.

CAUSE

By default, only host names are checked when the Bypass proxy server for local addresses option is turned on.

RESOLUTION

To bypass a range of IP addresses or a specific domain name, specify the addresses in the proxy exception list:
  1. In Internet Explorer, on the Tools menu, click Internet Options.
  2. On the Connections tab, click LAN Settings.
  3. Click Advanced, and type the appropriate information in the Exceptions area.

STATUS

This behavior is by design.
