User's IP address - is there a call to retrieve this?

Thank you in advance. I have looked for this here, and cannot find a definitive answer.

I realize that a visitor’s IP address usually changes from visit to visit. I am not trying to track a visitor from visit to visit.

I need to tie a visitor’s viewing of a page on my WIX site to a corresponding record in a log on an external tracking service - using the visitor’s IP addr for one particular visit. The external tracker logs visitor IP addresses, and it gives me more info about the visitor than I can gather on WIX.

QUESTION: Is a visitor’s IP address available via Corvid ?
