govuk-aws: 16. internal DNS zones

Date: 2017-07-19




We have a number of internal services that need to have internal only service records. This allows clients to connect within their own environment or stack without needing a fully qualified domain name.

These records should not be visible outside the local environment or stack.


We've bought a domain name that will not be connected to the rest of the public DNS system. This will be used by our internal services.

This domain will not have DNS records added to it.


We have a domain that we pay for and don't use.

If the registration ever expires, and we've incorrectly defined our search paths, someone could register it and influence our services. This risk is however present in all the domains we use.

This is also the approach taken by some of our sister teams.
