IP-Range in Limit-Moduls

Server NGINX
1

Hello,

Is there a chance to set an IP-Range with the “HTTP Limit Zone”
or the “HTTP Limit Requests” module?
Like 1.2.3.4/8 → ignore the last 8 bits of the internet address.

It would reduce the required zone-size and would help against
DDoS attacks.

Thanks
Marcus

You are free to use any variable in limit_zone/limit_req_zone. It
should be possible to produce needed variable with rewrite module
(or alternatively via embedded perl).
