What IP addresses are reserved for NGINX?

[YuS2rUQ1FXSkG1W]

I need to calculate RPS from IP addresses and detect its suspicious activity. I can do it via logs exploring.

I need to track only “external IP addresses” and addresses don’t belong to the “Nginx network”.

I can exclude unnecessary private IP addresses (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16). But I don’t understand what’s Nginx network IP addresses.

The example I got is mask like XXX.YYY… . I’ve tried to search such pattern through the whole configuration at the server where Nginx is deployed but have found nothing relevant.

Then I was told “I can get such addresses from Nginx documentation”. I’ve searched Nginx documentation but have found nothing like reserved IP addresses.

What am I missing?

To connect with NGINX Agent, you need to allow appropriate firewall rules through the following address ranges:

NGINX doesn’t have any reserved IP addresses. It uses the IP address(es) assigned to the environment (server, VM, etc.) in which it runs. It sounds like you are trying to discover what IP address range is assigned to the network in which NGINX is running.

To add to the above, you should be able to figure out which IP your machine is using by running either ipconfig or ifconfig depending on your OS
