OptionalexcludeWhether to exclude equivalent IP addresses from being treated as matching in IP comparison methods.
For example, IPUtil.contains returns true by default when two equivalent IP strings
are compared (i.e., this option defaults to false):
IPUtil.contains('fd12:3456:789a:1::/64', 'fd12:3456:789a:1:0:0:0:0/64'); // true
If this option is set to true, the comparison above will return false instead, since
identical CIDRs are not considered to form a containment relationship in that case.
