If your application server is behind a proxy, request.META["REMOTE_ADDR"] will likely return the proxy server's IP, not the client's IP. The proxy server will usually provide the client's IP in the HTTP_X_FORWARDED_FOR header. This util function checks both headers. I use it behind Amazon's Elastic Load Balancer (ELB).

def get_ip(request):
    """Returns the IP of the request, accounting for the possibility of being
    behind a proxy.
    """
    ip = request.META.get("HTTP_X_FORWARDED_FOR", None)
    if ip:
        # X_FORWARDED_FOR returns client1, proxy1, proxy2,...
        ip = ip.split(", ")[0]
    else:
        ip = request.META.get("REMOTE_ADDR", "")
    return ip
