Default service IP address and hostname#

Default service IP address#

When a new Aiven service is created, the chosen cloud service provider will dynamically assign one or more public IP address from their connection pool. This IP address is not permanent, and with every service maintenance (in case of failover, maintenance upgrade or cloud migration) the IP address changes since Aiven creates a new node, migrates the existing data to it and then retire the old node.


Aiven also offer the ability to define static IP addresses in case you need them a service. For more information about how to obtain a static IP and assign it to a particular service, please check the related guide.

If you have your own cloud account and want to keep your Aiven services isolated from the public internet, you can however create a VPC and a peering connection to your own cloud account. For more information on how to setup the VPC peering, check the related article.

Default service hostname#

When a new service is being provisioned, its hostname is defined as follows:



  • <SERVICE_NAME> is the name of the service

  • <PROJECT_NAME> is the name of the project

  • * is a variable component consisting of one or more levels of alphanumeric subdomains for the purpose of load balancing between DNS zones.


Second-level domain part of might change to another name in the future if the domain becomes unavailable for updates.


Always use a fully-qualified domain name returned by Aiven API. Make sure your code doesn’t put any constraints on the domain part or format of the returned service hostname.


If the <SERVICE_NAME> is too short or was recently used (for example, if you drop and recreate a service with the same name), the hostname format could be <SERVICE_NAME><3RANDOMLETTERS>-<PROJECT_NAME>.*
