Boffins supercharge the 'hosts' file to save users plagued by DNS outages
Wednesday, 26 April 2017 15:29

The venerable Domain Name System (DNS) is becoming known for fragility, and keeping track of your own favourite sites' IP addresses is a pain. So a group of researchers want to automate the upkeep of hosts to give users an emergency backup if their provider blacks out.
