TCP middleware InFlightConn connections per IP or global?

Available TCP middleware are the InFlightConn and IpWhiteList

The documentation page for InFlightConn is a bit confusing.

The header states that the middleware limits the number of simultaneous connections by IP. Later in the page, it states that " The amount option defines the maximum amount of allowed simultaneous connections." with no reference to "per IP" basis.

Does anyone know for a fact if the limit is on a per IP basis or is it global? Obviously, the configured number will change significantly based on the context (global or per IP).

Thanks in advance.

I would say the "per IP" is the general description and the details for the available options (just "amount") is not repeating it again.
