Domain Openness Through Continued Oversight Matters Act of 2014 or the DOTCOM Act of 2014 - Prohibits the Assistant Secretary of Commerce for Communications and Information from relinquishing or agreeing to any proposal relating to the relinquishment of the responsibility of the National Telecommunications and Information Administration (NTIA) over Internet domain name system functions (including the authoritative root zone file, Internet Assigned Numbers Authority functions, and related root zone management functions) until the Comptroller General (GAO), within one year after the NTIA receives a relinquishment proposal developed in a process convened by the Internet Corporation for Assigned Names and Numbers (ICANN) at the request of the NTIA, submits a report to Congress regarding the role of the NTIA with respect to the Internet domain name system.

Requires such GAO report to include: (1) advantages and disadvantages of such relinquishment of NTIA responsibility; (2) any principles or criteria that the NTIA sets for relinquishment proposals, as well as an analysis of each proposal received by the NTIA; (3) the processes used by the NTIA and any other federal agencies for evaluating proposals; (4) any national security concerns; and (5) a definition of "multistakeholder model" as used by the NTIA with respect to Internet policymaking and governance.
