Internet governance needs to make an ethical consensus，for promoting the system construction of the global Internet governance and achieving negotiation and cooperation among related stakeholders in society. The coherent balanced model provides an analytical framework for building an ethical consensus on Internet governance. In the framework，we analyze that the formation of ethical consensus of Internet governance needs to go through three stages：the setting of ethical bottom line，the establishment of utilitarian principle，and the flexible use of moral strategy. These three stages can not only be carried out at the level of progress，but also be interleaved to promote the construction of ethical consensus. This article further explores the ethical principles that should be followed in the three stages of ethical consensus，and concludes that the Internet governance needs to adhere to the ethical bottom line of “putting people first”，holding the concept of win-win development and carrying out the specific analysis of specific problems of moral strategies.
