#TIL : Curl override Name Resolution with specific IP address

You can overrride the Name Resolution with specific IP address without adding the hostname to /etc/hosts file by using --resolve option.

Syntax :

--resolve <host:port:address>

It will resolve IP address when connect to host on port

Example :

This will connect 127.0.0.1

$ curl --resolve google.com:80:127.0.0.1 "http://google.com/"

But this won't connect 127.0.0.1, because we use 443 port for https

$ curl --resolve google.com:80:127.0.0.1 "https://google.com/"

For cover all ports, use * wildcard

$ curl --resolve google.com:*:127.0.0.1 "https://google.com/"
