What are the public IP addresses to provision in a firewall configuration to allow Aura use?

There are three different groups of IP addresses you'll need to have access to in order to use Aura. They are:

• The address of the Aura console itself: 35.241.228.234
• The addresses of our Support Portal (what you're reading right now): 104.16.51.111 and 104.16.53.111
• The address(es) of your database(s).

That last group contains a number of different IP addresses. For our Professional tier customers, we have a collection of public IP addresses we use depending on the region your database is deployed in. For our Enterprise tier customers, you will have one or more dedicated IPs for your environment. If you need help finding that IP, please use this method.

To configure your firewall for access to your Neo4j Aura Professional tier (for Aura Enterprise please contact support) database you should include in the allowlist the relevant Aura public IP addresses based on your region(s):

(*) Port 80 is optional and only ever used to redirect to HTTPS. Not used for data communication.

Further details of physical location can be found here 

Notes:

To connect to Aura in your application, your URI will need to use the fully qualified domain name (FQDN) of your database, and not just the IP address.
For example, if your database ID is abcd1234, then the URI to use would be neo4j+s://abcd1234.databases.neo4j.io.
