The Domain Management team
at the Cabinet Office scan and monitor the .gov.uk domain name space to identify issues and help organisations fix them. We also monitor other name spaces where appropriate.
Most of our scanning is passive and does not require permission. Where scanning is more active we will ask you to complete this form to approve the activity.
