How to get registered users’ ip address

https://www.ads-software.com/extend/plugins/wassup/
this is a detailed stats plugin – it gives ip addresses when folks visit the site

I don’t want to track all visitors’ ip address. I just need to get current logged in users ip as a php variable. Is that possible?

I wouldn’t know how – maybe someone else will see this

this is sort of old but might give you some ideas
