[Dnsmasq-discuss] Uncensoring Sci-Hub.io: how to deal with subdomains & local DNS records?

[Simon Kelley]

I don't have much of a clue about this, but as you've asked on the
dnsmasq list, one dnsmasq-based thing you can do is enable


log-queries


in your dnsmasq configuration. That will tell you what queries are being
made, and what answers are coming back.


ETA. I wonder if the problem is reverse-lookups of  31.184.194.81
What does

dig -x 31.184.194.81

say?


Simon.
