United States government oversight of the Internet Corporation for Assigned Names and Numbers (ICANN) by the National Telecommunications and Information Administration (NTIA) was scheduled to end in October 2016. A prior agreement had ensured that the United States government must be consulted on any "modifications, additions, or deletions" to the root zone file which is maintained under subcontract by ICANN.http://www.ntia.doc.gov/files/ntia/publications/amend11_052206.pdf
