Automatic User Login


Classification Web can be configured so that any access from a specific IP (Internet Protocol) address or range of addresses will automatically log that computer into a particular account.  In order to do this, the IP (Internet Protocol) address of either the end-user's computer or the network it is attached to must always be the same (static) and this value must be assigned to either that user or their institution.  It is the end-users's responsibility to properly configure their account so that only authorized users of that account can login in this manner.  In general, only educational, government and corporate networks have static IP addresses.  Most other users are assigned a different IP address every time they connect to the Internet.  Users should check in with their technical services department or Internet Service Provider (ISP) to determine if they have a static IP address and for assistance in configuring this information in ClassWeb.

Work-from-home: With the increasing trend of work-from-home arrangements, your institution can set up a proxy server within its physical campus to provide access to subscription services like ClassWeb. Please contact your IT department for more information on this option. From the point of view of ClassWeb, if you want to be able to use auto-login from a location other than your office, you would configure your proxy server accordingly and add the IP addresses of the proxy server to the list in your ClassWeb account configuration (see below).

Once you have associated one or more IP addresses with your account, you must use the Classification Web auto login menu when starting your session in order to log in automatically.  Any time you start a session in this manner, you will be restricted to read-only access to your account.  If you need the ability to edit your local notes and change your preferences, you must start your session from the standard menu, which will not log you in automatically.  If you use the standard menu and are not prompted for your user name and password, it means that you are already running a Classification Web session.  In this case, log out of Classification Web, return to the standard menu and make your selection again.

To configure your account to allow for automatic user logins, use the Settings link found on the drop-down menu at the top-left corner of every page. From the Settings Menu click on Account Settings and select the Login tab. In the text box labelled Automatic Login by IP Address (Advanced Feature) you can list one or more IP addresses that can log in automatically. Each ip address should be on a separate line. When you have made all of your changes, click on the Save button on the upper-right corner of the page.

IP Addresses
An IP address contains four decimal numbers, separated by periods (i.e.  To input a network address (a range of IP addresses), follow the IP address by a slash (/) and a network mask from 8 to 31 that indicates how many bits at the front of the address make up the network address (for example, the value of refers a network address of, which includes the range of IP addresses from to  Please note that any IP addresses you input with network masks will be normalized when you save your preferences so that only the network address will remain.  For example, the value of will be converted into

If your network administrator has given you a network address with asterisks (*) in it, you must convert this value by replacing the asterisks with zeros and appending a network mask (a slash followed by a number) as follows:

  Network Mask
 192.168.1.* becomes
 192.168.*.* becomes
 192.*.*.* becomes

You can tell if the auto-login feature is working by accessing Classification Web through the auto login menu.  If you can start a new ClassWeb session without having to log in, everything is working properly (make sure you weren't already logged in by clicking on the Sign out link on the Navigation menu first). If you get a login screen, something has been misconfigured. The most likely reason is that the computer you are using to access ClassWeb is not at the IP address you expected.  There is a ClassWeb Diagnostics Page to help you track down these types of problems (you don't have to be logged into ClassWeb to use it). This page returns the web browser version, domain name and IP address of the computer making the request.
