How to manage DNS records for your service
To ensure users can connect to your service, you’ll need accurate Domain Name System (DNS) records and a DNS provider to supply your DNS nameservers.
You can find information on choosing where to host your DNS and how to request nameserver delegation at GDS in the Service Manual.
As part of your DNS strategy and planning you need to ensure your:
- DNS entry configuration (stored for example in a zone file using JSON or YAML) is version controlled unless it’s autogenerated
- overall service strategy includes nameserver high availability, for example deploy publishing.service.gov.uk to both Amazon Route 53 and Google Cloud DNS
When you implement your DNS strategy you should consider using:
- Amazon Route 53 as a cloud DNS web service
- Google Cloud DNS or Dyn for high nameserver availability
- version control to publish your records using tools such as GOV.UK DNS or octoDNS
You can read more about service domains and DNS in the Service Manual.
