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—195.92.40.49 and 62.25.106.209. These IP addresses are shared with other Government Departments that use the Government secure intranet.
