-The peer definitions can be in any order. They are checked
-most-specific first, and searching stops as soon as a match is found.
-Therefore a default definition can be added as
-.IP
-.I tag
-.B =
-.B 0/0
-.PP
-without fear of overriding any more specific definitions. For avoidance
-of doubt, one peer definition is
-.I more specific
-than another if either the former has a specified
-.I remote-addr
-and the latter has not, or the former is wholly contained within the
-latter. (Overlapping definitions are not recommended, and will be
-processed in an arbitrary order.)
+The peer definitions in each group are checked in the order given, and
+searching stops as soon as a match is found. (In older versions of
+.BR conntrack ,
+definitions were processed according to a most-specific-first order, but
+that doesn't provide an ordering between IPv4 and IPv6 networks, which
+is important; so this has been changed.)
