IP address lookup still happens with requests_mock?

How to prevent calling socket.gethostbyname while using requests_mock?
I still see DNS query sent out even though I mock the url.

Haven't looked into too deep, but I thought the mock adaptor should intercept before IP address lookup?

Here is the code to reproduce
I'm using python3.11

import requests_mock
import requests

url = "https://random.dev"
with requests_mock.Mocker() as m:
	m.get(url, text="test")
	resp = requests.get(url)
	assert resp.text == "test"

And then use tcpdump -i any udp port 53 (may need sudo) to monitor DNS traffic.

That is interesting - and I would agree, at the point we hook into requests should be well before any DNS resolution happens.

From your snippet and tcpdump though I can't reproduce. There's a decent chance though on my current macbook with some corp settings that there might be like DNS over TLS or other new thing configured, but i do see some DNS traffic.

Can someone else confirm if they see this as well?
