How to Update or Remove IP Ranges for IP Authentication

This article explains how IP authentication updates are handled and what to do when changing IP-based access.

What happens when IP authentication is enabled?

IP authentication grants access based on the device's IP address. Users signing in from a configured IP range bypass the login prompt and are granted access automatically. Users outside a configured range will be required to authenticate normally.

How does IP authentication affect user differentiation?

When IP authentication is enabled, all users connecting from a configured IP range — including both staff and students — are granted access without individual credential checks. This means role-based differentiation (e.g., staff vs. student permissions) is not applied during IP-authenticated sessions.

How can I update or remove IP ranges for access?

To update or remove IP ranges:

1. Compile the IP ranges you want included or removed.
2. Send the confirmed list of IP ranges to the support team and request the change.
3. Support will apply the changes to the system. For removals, the specified IPs will be deleted from the configuration. Note that changes may take up to one business day to take effect.

Can IP authentication be re-enabled after removal?

Yes. IP authentication can be re-enabled on request. If IP ranges were previously removed, confirm the ranges to be added when requesting re-enablement.

What alternatives help route users to single sign-on?

To route users directly to single sign-on (SSO), embed the platform’s ACS URL or a SAML DeepLink in your systems. This bypasses the generic login page and sends users directly to your organisation's SAML portal. Contact support to obtain the correct ACS URL or DeepLink for your configuration.

Troubleshooting: users seeing sign-on errors off campus

If off-campus users are experiencing sign-on errors, temporarily re-enabling IP authentication can restore access while your SSO configuration is reviewed and corrected. To request this, contact the support team with a description of the issue and the affected user group.

Conclusion Confirm the exact IP ranges you want included or removed, and submit them to support when requesting updates. Re-enabling IP authentication and embedding ACS/SAML links are available options to manage campus and off-campus access.
