   Dear uniFLOW Online Customer, **Description:** This notification is to inform you that NT-ware will be expanding its public cloud global infrastructure. Please take note on the below changes and update your firewall policy rules to allow the new URL and IP address ranges to avoid any service disruption. **What is changing:** - We will be making the following changes which will take effect from the 20th of November 2025. - There will be a new IOT Hub published in the UK: ukiothub1uniflow.azure-devices.net **What do I need to do:** Review our DNS and IP addresses - https://dns-ip-list.uniflowonline.com/ for your specific deployment region, full change history can be found at the bottom of the page. You must update your firewall policy rules and/or any upstream ACL(s) to allow the new IP address ranges for your given deployment region for the given date. **Who does this apply to?** This is ONLY needed for customers that are explicitly blocking internet traffic at their firewall. It is NT-ware's recommendation that customers use DNS entries in their firewall where possible to adapt to IP address changes should they occur. **Support or questions?** Should you need further support or have questions please raise this with your Canon Direct / Partner Sales Support representative.
