Permit/deny lists and behavior

[Marki]

Hello,

Maybe someone can enlighten me:

The default seems to be that
* dynamic address assignment to unknown clients is allowed ("allow 
unknown-clients" is implicit) and
* at the same time static allocations are allowed as well ("allow 
known-clients" is implicit).

This is kind of a contradiction to "If a pool has a permit list, then 
only those clients that match specific entries on the permit list will 
be eligible to be assigned addresses from the pool."

Or does that mean if I explicitly write "allow known-clients", then 
unknown clients will be rejected?  Is "unknown-clients" a "list" in that 
regard?

Best regards,
Marki
