I need to get Client's IP to define their role in my website.
I already asked similar question here Get client IP address Angular but failed to do so.
I read that X_FORWARDED_FOR includes client's ip and proxy. I tried to get XFF from frontend but failed. Or XFF can only be accessed from backend?
Is it possible to get Client's IP from frontend? or I need to get it from the backend (I use grails)? Or maybe anyone have tips to how I can get Client's IP (either i get it from frontend or backend)
I'm a newbie frontend developer and need help. Thank you
