Start with [Managing Microsoft 365 endpoints](managing-office-365-endpoints.md) to understand our recommendations for managing network connectivity using this data. Endpoints data is updated as needed at the beginning of each month with new IP Addresses and URLs published 30 days in advance of being active. This cadence allows for customers who don't yet have automated updates to complete their processes before new connectivity is required. Endpoints may also be updated during the month if needed to address support escalations, security incidents, or other immediate operational requirements. The data shown on this page below is all generated from the REST-based web services. If you're using a script or a network device to access this data, you should go to the [Web service](microsoft-365-ip-web-service.md) directly.
