I have a GET request with header params and I want to check which db instance my app is using. Is there a way I could build a cURL request that would tell me where my request is going? I know there is a traceroute command which displays all the server hops. But is there something similar to that using a cURL?

For a slightly better formatted output to stdout 

curl --trace-ascii - <host>

You can use --trace option: --trace FILE Write a debug trace to FILE

curl --trace trace.txt yourdomain.com

(You cannot use trace and verbose at the same time, trace overrides it)

    I tried this, but the resulting file doesn't seem to display the IP addresses of the machine at each hop of the request. – BobbyA Mar 25 '19 at 21:01

curl -L -v --noproxy '*' --trace-ascii data.txt https://example.com

-L will follow the redirects

-v is for verbose

--noproxy '*' This flag instructs curl to not use any proxy and connect directly to https://example.com

--trace-ascii data.txt : Will store the output in data.txt
