PSN Core Services

Buy Domain Name System (DNS) services that allow government users of the Public Services Network to send electronic information securely.


This agreement provides Public Services Network (PSN) Domain Name Server (DNS) services that reconcile website names and their underlying IP addresses and allow the government and the wider public sector to send digital information securely.

The agreement has been developed in collaboration with the Government Digital Service and will replace the Government Convergence Framework (GCF) DNS service which will end on 31 March 2021. If you are a user of the GCF service you will need to re-contract and migrate to this replacement service.

The PSN is the government’s high-performance network, which helps public sector organisations work together to share information and resources and reduce duplication. 

A DNS maintains a directory of website names (known as domain names), for example,, and translates them into IP (Internet Protocol) addresses. This is necessary because computers and machines don’t understand website names and need an IP address to access a website.
