+ An expression of the form `n.n.n.n/m.m.m.m\' is interpreted as a
+-`net/mask\' pair. A host address is matched if `net\' is equal to the
++`net/mask\' pair. An IPv4 host address is matched if `net\' is equal to the
+ bitwise AND of the address and the `mask\'. For example, the net/mask
+ pattern `131.155.72.0/255.255.254.0\' matches every address in the
+ range `131.155.72.0\' through `131.155.73.255\'.
+ .IP \(bu
++An expression of the form `[n:n:n:n:n:n:n:n]/m\' is interpreted as a
++`[net]/prefixlen\' pair. An IPv6 host address is matched if
++`prefixlen\' bits of `net\' is equal to the `prefixlen\' bits of the
++address. For example, the [net]/prefixlen pattern
++`[3ffe:505:2:1::]/64\' matches every address in the range
++`3ffe:505:2:1::\' through `3ffe:505:2:1:ffff:ffff:ffff:ffff\'.
++.IP \(bu
+ Wildcards `*\' and `?\' can be used to match hostnames or IP addresses. This
+ method of matching cannot be used in conjunction with `net/mask\' matching,
+ hostname matching beginning with `.\' or IP address matching ending with `.\'.
