Guides - Manage Access Controls
Fully managed cloud database clusters built on top of Linode’s trusted and reliable platform.
Each Managed Database cluster has its own access control list, which allows specific IPv4 addresses or ranges to connect to the database. By default, all connections (both public and private) are blocked unless they appear on this list.
View Access Controls
Log in to the Cloud Manager and select Databases from the left navigation menu.
Select your Managed Database from the list. This opens the detail page for that database cluster.
Within the Summary tab, access controls appears under the Access Controls section. A list of each allowed IP address or range is displayed.
Types of Access
No access (blank): If no IP addresses are provided, the database will not allow any connections.
Open access (
0.0.0.0/0
): Entering an IP address of 0.0.0.0/0 allows connections from any IP address.Individual access (
192.0.2.1/32
): To grant an individual system access, enter that system’s IPv4 address. The/32
is added automatically if no prefix size is provided, which means only this single IPv4 address is included within this rule.Range access (
192.0.2.0/24
): Allow connections from an entire range of IP addresses by specifying the prefix and the prefix length. For instance, entering 192.0.2.0/24 as an access control allows connections from 192.0.2.0 - 192.0.2.255.
