We're making changes to the IP addresses used by GitHub Enterprise Importer for outbound network connections. These changes will take affect at 00:00 UTC on September 18, 2023.

If you're running migrations with GitHub Enterprise Importer and you have IP allowlisting enabled on your migration source or target, or an Azure Blob Storage or Amazon S3 account which you use for migrations, then you'll need to update your allow list.

For a full list of our IP ranges and more information, see "Configuring IP allow lists for migrations" in the GitHub Docs (https://docs.github.com/en/migrations/using-github-enterprise-importer/preparing-to-migrate-with-github-enterprise-importer/managing-access-for-github-enterprise-importer#configuring-ip-allow-lists-for-migrations).
