I think as granular as practicable. In some cases, that will be a /32 or =
/128. In some cases, that will be a /24 or /64.

In some cases, it may be an entire ASN.

Each network will need to decide for themselves based on the constraints =
of the time they have to address the issue, the level of automation for =
addressing these things, memory in their routing platform(s), etc.

There is no one-size-fits all answer.
