Thanks for the info :) For now I will just stick with what I know is currently working either way I believe the stored key in memory won't be compressed due to being behind cloudflare's reverse proxy as you said only $binary_remote_addr is compressing their IP to reduce memory footprint.

Here is my config for anyone who wants to test or play around same as in original email.

map $http_cf_connecting_ip $client_ip_from_cf {
default $http_cf_connecting_ip;
}

limit_req_zone $client_ip_from_cf zone=one:10m rate=30r/m;
limit_conn_zone $client_ip_from_cf zone=addr:10m;

location ~ \.mp4$ {
limit_conn addr 10; #Limit open connections from same ip
limit_req zone=one; #Limit max number of requests from same ip

mp4;
limit_rate_after 1m; #Limit download rate
limit_rate 1m; #Limit download rate
root '//172.168.0.1/StorageServ1/server/networkflare/public_www';
expires max;
valid_referers none blocked networkflare.com *.networkflare.com;
if ($invalid_referer) {
return 403;
}
}
