DNS, or Domain Name System, serves as the internet's directory, translating human-readable domain names into machine-readable IP addresses (e.g. "xkcd.com" => 151.101.0.67). This translation allows users to access websites, send emails, and utilize other internet services using familiar domain names instead of numerical IP addresses.

EWC provides DNS to each tenancy and it has the following specifications:

• The DNS record assigned to each machine has the following pattern <machine-name>.<tenancy-name>.<hosting-location>.ewcloud.host where: 
  • hosting-location:  f means an ECMWF-hosted VM and s means a EUMETSAT-hosted VM
  • tenancy-name: "mytenant" that you can find from this page Logging in to Morpheus or (only for tenancy admins) go to Administration → Users → Identity Sources

• • machine-name: no space or dot characters are allowed in the VM name, if you provision a VM with spaces or dots in the name, the record won't be created. Also, if the name has capital letters, the domain will use lowercase letters.
  • Example: myvm.example_tenancy.s.ewcloud.host
• The DNS record is created after provisioning a machine in Morpheus and it is available after some time (up to 15 minutes).
• If a machine has both a private and a public IP, the public IP will be assigned to the DNS record.  If you need the private IP instead, please raise a ticket.

These default DNS names are intended to allow simpler usage when testing or developing.  If you wish to run a public-facing service, we recommend additionally using a specific (or your organisation's) DNS domain.  For advice, feel free to contact us.
