6.2 DNS services in cPouta

cPouta does not currently offer integrated nameservice management.

All our floating IPs are mapped to a default hostname, for example


To use your own DNS name for your virtual machine, simply configure your own DNS server to point the domain name to the floating IP that the virtual machine is using.

For most services these forward DNS records are enough. Some services also require reverse DNS lookups to work. This means that we have to configure our DNS server to say that the floating IP you are using resolves to the domain name your are using.

You can request reverse DNS mappings.

  • Point the DNS name to the server you want.
  • Send a mail to cloud-support@csc.fi with the IP / hostname pair you want to be mapped. Also send the UUID on the virtual machine it should be mapped to. You do not need to send mail if the floating IP is moved to another machine, as long as the domain info for the floating IP still is correct.
  • When you no longer need the mapping, please contact cloud-support@csc.fi so we can remove the reverse DNS entry.

We reserve the right to clean up old reverse DNS records where the forward DNS records do not match anymore. We will also remove the reverse records when closing the project.
