Schema for IP-based client ACLs: :ref:`server-plugins-misc-acl` ``ip.xml`` The name of the XML-RPC method to allow or deny. Limited wildcards are supported. The IP address to match against. This is an exact match unless :xml:attribute:`IPACLType:netmask` is defined. If this is not defined, all addresses match the given rule. If this is defined, then it is combined with :xml:attribute:`IPACLType:address` to produce a CIDR range, which is used for matching instead of exact matching based only on IP address. This can be either an integer netmask (e.g., ``netmask="24"``) or a dotted-quad (e.g., ``netmask="255.255.255.0"``). Top-level tag for describing metadata-based client ACLs.
