A positive integer between [1, Int32.MaxValue-1] that defines the order of
rule evaluation. Rules with the lowest priority are evaluated first.
A default rule at priority Int32.MaxValue matches all IPv4 and IPv6 traffic
when no previous rule matches. Only the action of this rule can be modified
by the user.
IP address or range, defined using CIDR notation, of requests that this
rule applies to. You can use the wildcard character "*" to match all IPs
equivalent to "0/0" and "::/0" together.
Examples: 192.168.1.1 or 192.168.0.0/16 or 2001:db8::/32
or 2001:0db8:0000:0042:0000:8a2e:0370:7334.
<p>Truncation will be silently performed on addresses which are not
properly truncated. For example, 1.2.3.4/24 is accepted as the same
address as 1.2.3.0/24. Similarly, for IPv6, 2001:db8::1/32 is accepted
as the same address as 2001:db8::/32.
