A powerful Senator is starting to ask NTIA questions about IP addressing. On October 4, 2011, The U.S. Senate Commerce Committee's chairman, Senator Jay Rockefeller, sent a challenging but private letter to the administration official responsible for overseeing ICANN, Lawrence E. Strickling. IGP has obtained a copy of the letter through the US Freedom of Information Act. The letter, which poses 22 tough questions, focuses not on the old controversies related to new gTLDs, but on the IANA contract.
