Internet has been being becoming the most famous and biggest communication networks as social, industrial, and public infrastructure since Internet was invented at late 1960s. In a historical retrospect of Internet's evolution, the Internet architecture continues evolution repeatedly by going through various technical challenges, for instance, in early 1990s, Internet had encountered danger of scalability, after a short while it had been overcome and successfully evolved by applying emerging techniques such as CIDR, NAT, and IPv6. Especially this paper emphasizes scalability issues as technical challenges with forecasting that Internet of things era has come. Firstly, we describe the Identifier and locator separation scheme that can achieve dramatically architectural evolution in historical perspective. Additionally, it reviews various kinds of Identifier and locator separation scheme because recently the scheme can be the major design pillar towards future of Internet architecture such as both various clean-slated future Internet architectures and evolving Internet architectures. Lastly we show a result of analysis by analysis table for future of internet of everything where number of Internet connected devices will growth to more than 20 billion by 2020.
