Coordinated version control to maintain consistency across documentation updates, emphasizing clarity and technical accuracy. Utilized skills in documentation and version management to streamline the update process. The work addressed the need for up-to-date network information, supporting developers and administrators who rely on precise IP address documentation for Microsoft Graph Change Notifications integration.
