DNS guidelines

DNS name

It is possible to ask CINECA for a DNS name association to the virtual machine by sending an email to superc@cineca.it.

In CINECA DNS, it is necessary to comply with the following rules:

• The reverse of the Floating IP (PTR record) must be set to the hostname of the VM, with the following naming convention:

  • for external users: <VM-name>.ext.cineca.it

  • for CINECA staff: <VM-name>.cineca.it

• The record A in the DNS is set accordingly to the previous point.

• If the service should be exposed with a different name, you can ask to set the CNAME with the chosen different name. If no other information is provided, only the record A will be set.

Additionally, you might set up a CNAME with your DNS provider of choice.

It is not possible to set the PTR record in CINECA DNS, if the record A has been set on an external DNS.
