The IP::addr iRule can be used to translate an IPv6 address containing an IPv4 address, but instead it converts it into an IPv4 compatible IPv6 address. Example: ltm rule test_bug { when CLIENT_DATA { log local0. "[IP::addr 2A01:CB09:8000:46F5::A38:1 mask ::ffff:ffff]" } Expected result: Rule /Common/test_bug <CLIENT_DATA>: 10.56.0.1 Actual result: Rule /Common/test_bug <CLIENT_DATA>: ::10.56.0.1
Address is converted into an IPv4-compatible IPv6 address.
