multiple `zone' clauses for a single domain?

[Marek Kozlowski]

:-)

One more question:
The documentation for `match-clients' isn't comprehensive enough... Can
I add all host from, for example 172.16/16 except a single host? Does:

match-clients { 172.16.0.0/16;!172.16.1.1; }

form an AND or an OR?

Best regards,
