IP addresses are automatically identified from the HTTP headers of web requests. However, in case load balancers, CDN's or proxies are used, the remote IP of the HTTP(S) request might be different from the original IP address from your user devices. Therefore, Dynatrace watches also the HTTP headers that are most frequently used for identifying the originating IP address of a client connecting to a web server through an HTTP proxy, a CDN or a load balancer.
To view the supported headers, go to Settings > Web and mobile monitoring > IP determination.
Process the default headers
You can change the order the default headers are processed. Just use the up and down arrows provided next to each header name. In case you don't want a header to be used, you can simply delete it by clicking the x symbol on the same row with the header's name. Also, by clicking the pencil icon, you can rename a header.
