Summary
This section covers some of the key services that need to be considered when migrating from one IP address scheme to another, and the appropriate action required to ensure minimal disruption.
Website URLs
Locally hosted web site domain names and their associated IP addresses are registered and updated using the DNS registration form on the NHS Digital website. When changing the external IP address scheme of a locally hosted service, it is essential this form is completed to ensure the correct DNS name entry and IP address appears within the national DNS table.
To ensure the changeover is co-ordinated in a controlled manner, the end user site can specify to NHS Digital when the change is to be activated.
Authentication services
End sites that host or access services that authenticate using the IP address need to ensure changes to advertised IP addresses at either the client or host site, are co-ordinated at both end user sites.
GP firewall rule table
Changes to GP firewall rule tables to allow new incoming sessions into the GP LAN should be requested through your network service provider.
