Departmental Internet

Volume 486: debated on Thursday 15 January 2009

To ask the Minister for the Olympics with reference to the answer of 4 November 2008, Official Report, columns 336-37W, on Government departments: information and communications technology, which IP addresses are used by (a) her Office and (b) computers in (i) her private office, (ii) the offices of its communications officials and (iii) the offices of her special advisers. (241958)

To help defend against electronic attack, it is standard good information security practise for corporate IT systems, not to publish internal IP addresses. When accessing internet websites, the IP addresses of all of the computers on the Cabinet Office’s internal office IT system are hidden behind the following IP addresses which are publicly available— and These IP addresses are shared with other Government Departments that use the Government secure intranet.
