DNS is one of the nerves of the Internet as it is used to resolve IP addresses to numbers. This is a critical service provided by ISPs and domain name registrar services.
Apparently Google is taking a step closer to become The Internet by providing free, open DNS services to any web site in the world. This news is making nervous almost all ISP providers, domain registrar companies, and large organizations like Microsoft.
They claim they are doing it to speed up the Web and to improve security (DOS, DNS Cache, DNS request attacks, topics covered in the Internet Engineering 1 course).
Their DNS service might evolve into a global connectivity ecosystem.
