 The maximum rate defined by a limit may be absolute or specific to
 blocks of IP addresses or pairs thereof. The number of most
 significant bits taken into account when mapping the source and
-destination IP addresses to blocks can be specified with the **mask**
-attribute. The **mask** attribute is an object with two attributes
-defining the prefix lengths, named **src** and
-**dest**. Alternatively, the **mask** object may have object
-attributes named **inet** and **inet6** which contain address
-family–specific prefix length pairs. If **mask** is defined as
-an integer, it is interpreted as the source address prefix length.

-The default value for **mask** depends on the type of the enclosing
-object. For [filters](#filter), the default behavior is to apply the
-limit for each source address separately. For [logging classes](#log),
-the limit is considered absolute by default.
+destination IP addresses to blocks can be specified with the
