Examples with IPAddressString inet.ipaddr.IPAddressString used on opensource projects

Example 1 with IPAddressString

use of inet.ipaddr.IPAddressString in project jcasbin by casbin.

the class BuiltInFunctions method ipMatch.

/**
 * ipMatch determines whether IP address ip1 matches the pattern of IP address ip2, ip2 can be
 * an IP address or a CIDR pattern. For example, "192.168.2.123" matches "192.168.2.0/24"
 *
 * @param ip1 the first argument.
 * @param ip2 the second argument.
 * @return whether ip1 matches ip2.
