A few years back, frustrated with increasaed DNS blocking of Sci-Hub, I wrote a quick DNSMasq hack (haq?) to return Sci-Hub IPs for any "sci-hub.<domain>" possible. The shins-n-grits factor of surfing "scihub.elsevier.com" were palpable.

As others have mentioned, Sci-Hub also maintains a Tor presence, and you can access the Onion link using the Tor browser (provided you can install that on your desktop or device).
