Thank you for your help.

I have solved the problem. Like you said, I used the IPv6.

I still don't want to add IPv6 to the whitelist. Because, in our organization,
we just beginning to survey IPv6 network system.
If the IPv6 network system is ready. I will add our IPv6 address to the
whitelist as soon as I can.

At last, I am very thank you for solving my question.
