I am running the latest version of curl (7.76.1).
I have set up my own dnsdist server / doh proxy which queries to a bind9 resolver I set up as well.
What is the right syntax to get curl to return only the resolved IPs?
When I run the following, All that is returned is example.com's html. I do not want the html. I want the resolved DNS IP addresses.
curl --doh-insecure --doh-url https://10.10.10.10/dns-query http://www.example.com
If I run with verbose output I can see the following.
* DOH A: 93.184.216.34* DOH AAAA: 2606:2800:0220:0001:0248:1893:25c8:1946How do I get curl to only return the DNS dig response, and not the response from a HTTP GET request to the site in question?
Here is the full output:
