ID ranges can show IDs in the billions when you run eSync after creating new content, menus, taxonomies, users, and so on.
eSync causes these large numbers to appear.
While the IDs may look a bit alarming, these large numbers are normal for sites that use eSync.
Each server that is in the eSync relationship gets its own set of IDs. The original server should contain low ID numbers, but any server with which it syncs will have IDs that start in the millions or billions.
The numbers are created to allow 2 databases to synchronize and to prevent duplicate ID numbers from being created, which would cause further errors and issues. You cannot alter or update these numbers.
