You can't speak with IP in some Baidu Post Bar that allows you to speak with IP.

Some Baidu Post Bar must require login to speak.

In other words, speak with an ID.

This should have nothing to do with whether it is your IP or not.

Because your new IP is not blocked.

You can speak directly with IP without logging in.

Some are ok, but not all.

If you don't want to show your ID card when you talk

You can choose "speak anonymously" when you speak.

I hope I can help you!
