You can enable the MultiCIDRServiceAllocator feature gate. The API server supports migration from the old bitmap ClusterIP allocators to the new IPAddress allocators.

The API server performs a dual-write on both allocators. This feature gate disables the dual write on the new Cluster IP allocators; you can enable this feature gate if you have completed the relevant stage of the migration.
