HSCN IP address management

The Health and Social Care Network (HSCN) programme will provide new and significantly different network services to the N3 network it succeeds.

HSCN will create the effect of a single network across health and social care providers and their partners. It will support more integrated care and is available to all health and social care organisations in England. 

HSCN Internet Protocol address management process

As part of your migration to HSCN, you may want or need to migrate your existing IP addresses. This will be managed by the Internet Protocol Address Management (IPAM) team.

NHS Digital will manage and administer the HSCN IP addressing policy and the IPAM function. The IPAM team will manage the allocation and return of subnets from the HSCN IP address space.

Please note that from 1st May 2018 the IPAM team only accept IPAM requests via the IPAM online forms in the HSCN portal. Please contact ipamteam@nhs.net for further information.

  1. Complete an IPAM form via the HSCN portal.
  2. The IPAM team will acknowledge your submission within five working days.
  3. Your requested IP addresses and migration date will be reviewed by the IPAM team, and every effort will be made to meet your requirements.
  4. The IPAM team will send an email confirmation within ten working days from the date of acknowledgement or contact you if further details are required.

Requirement for additional IP addresses

If you require an additional allocation of IP addresses, then please complete the HSCN Private IP Address Allocation Request form and return by email to ipamteam@nhs.net.

This form is only for organisations with sites already connected to HSCN that have a requirement for an additional allocation of IP addresses from the NHS private IP address space; 10.0.0.0 - 10.255.255.255. 

This form should not be used to request NHS private IP address allocations for sites connected to the Transition Network (legacy N3).
