詳細描述

This rule returns true if the given IP address is within a certain range. Use the constructor or the setRange() method for setting the right range. The range should be given in a submask format, so for example 1.2.3.4 would be within the range 1.2.3.255

It will set the error flag ERROR_RULE_IP_NOT_IN_RANGE error if the address is not in the given range.
