The add-on is $4 per month - we're passing on the AWS costs to you. The add-on is available for all paid plans.
|
|
|
|
## When is this add-on required?
|
|
|
|
This add-on is not required if any of these conditions are met
|
|
|
|
- you are only connecting to the database via Supavisor, our connection pooler, or via any of our client libraries.
|
|
- If you are connecting to the database directly and the network from which you are connecting to the database supports IPv6 addresses.
|
|
|
|
This add-on is only required if you are connecting to the database directly from an IPv6 incompatible network.
|

<Admonition type="note" label="Add-on has no impact on PGBouncer removal">
|
|
|
|
When you purchase this add-on, your project won't be migrated to IPv6. PGBouncer will still be removed for the project according to the timeline mentioned in [this discussion](https://github.com/orgs/supabase/discussions/17817);
|
|
|
|
</Admonition>
|
|
|
|
## Enabling the add-on
|
|
|
|
You can enable the IPv4 add-on in your project [add-on settings](https://supabase.com/dashboard/project/_/settings/addons) page.
|
|
|
|
<Admonition type="caution" label="Downtime when add-on is toggled.">
|
|
Note that there might be some downtime when toggling the add-on since some DNS clients might have
|
|
cached the old DNS entry and it might take some time for the updated DNS entry to be picked up.
|
|
Generally, this should be less than a minute.

## Read Replicas
|
|
|
|
When the IPv4 add-on is enabled, an IPv4 address is provisioned for each database in your project.
|
|
|
|
By default, this is only the Primary database for your project. If [Read replicas](/docs/guides/platform/read-replicas) are being used, each replica also gets its own IPv4 address, with a corresponding $4 charge.
|
|
|
|
## Caveats
|
|
|
|
For regular use-cases like a restart or compute size changes, the IPv4 address remains unchanged.
|
|
However, there are cases where maintaining the same IPv4 address isn't guaranteed. These include:
|
|
|
|
- If the project gets paused and unpaused
|
|
- If the add-on gets removed and added again
