Weirdness - IP Address blocked?

Could you please describe your query in more detail? Which IP address seems to be blocked, and where?

Or are you perhaps asking about how to block certain IP addresses from filling out your forms?

In case that you wish to limit your form submissions to only receive one submission from any specific IP address, you can do so by using Preferences > Form Limits and setting Unique Submission to Strict Check.

Please let us know about your specific question in more detail, and we will be happy to help.
