Note: HTTP header HTTP_X_FORWARDED_FOR will give you multiple addresses

During testing, this never showed up on the dev servers. The reason is that we only get one IP for HTTP_X_FORWARDED_FOR, unless we're behind a load balancer or HTTP proxy.

The correct method of using this is:

view sourceprint?

1.if 'HTTP_X_FORWARDED_FOR' in request.META:

2.  question.ip = request.META.get('HTTP_X_FORWARDED_FOR').split(',')[0].strip()

3.else:

4.  question.ip = request.META.get('REMOTE_ADDR', None)

This will get the client IP (first position) and strip out any spaces.

If there is no forwarded IP, it'll resort to using the REMOTE_ADDR header.

The code is written in Python but should be easily portable to any other language.
