title: 'Dedicated IPv4 Address for Ingress'
description: 'Attach an IPv4 address to your database'
subtitle: 'Attach an IPv4 address to your database'
---
The Supabase IPv4 add-on provides a dedicated IPv4 address for your Postgres database connection. It can be configured in the [Add-ons Settings](/dashboard/project/_/settings/addons).
## Understanding IP addresses
The Internet Protocol (IP) addresses devices on the internet. There are two main versions:
- **IPv4**: The older version, with a limited address space.
- **IPv6**: The newer version, offering a much larger address space and the future-proof option.
## When you need the IPv4 add-on:
<Admonition type="caution">
IPv4 addresses are guaranteed to be static for ingress traffic. If your database is making outbound connections, the outbound IP address is not static and cannot be guaranteed.
</Admonition>
- When using the direct connection string in an IPv6-incompatible network instead of Supavisor or client libraries.
- When you need a dedicated IP address for your direct connection string
## Enabling the IPv4 add-on
You can enable the IPv4 add-on in your project's [add-ons settings](/dashboard/project/_/settings/addons).
You can also manage the IPv4 add-on using the Management API:
```bash
# Get your access token from https://supabase.com/dashboard/account/tokens
export SUPABASE_ACCESS_TOKEN="your-access-token"
export PROJECT_REF="your-project-ref"
# Get current IPv4 add-on status
curl -X GET "https://api.supabase.com/v1/projects/$PROJECT_REF/billing/addons" \
-H "Authorization: Bearer $SUPABASE_ACCESS_TOKEN"
# Enable IPv4 add-on
curl -X PATCH "https://api.supabase.com/v1/projects/$PROJECT_REF/billing/addons" \
-H "Authorization: Bearer $SUPABASE_ACCESS_TOKEN" \
-H "Content-Type: application/json" \
-d '{
"addon_variant": "ipv4_default",
"addon_type": "ipv4"
}'
# Disable IPv4 add-on
curl -X DELETE "https://api.supabase.com/v1/projects/$PROJECT_REF/billing/addons/ipv4_default" \
-H "Authorization: Bearer $SUPABASE_ACCESS_TOKEN"
```
<Admonition type="caution">
Note that direct database connections can experience a short amount of downtime when toggling the add-on due to DNS reconfiguration and propagation. Generally, this should be less than a minute.
</Admonition>
## Read replicas and IPv4 add-on
When using the add-on, each database (including read replicas) receives an IPv4 address. Each replica adds to the total IPv4 cost.
## Changes and updates
- While the IPv4 address generally remains the same, actions like pausing/unpausing the project or enabling/disabling the add-on can lead to a new IPv4 address.
## Supabase and IPv6 compatibility
By default, Supabase Postgres use IPv6 addresses. If your system doesn't support IPv6, you have the following options:
1. **Supavisor Connection Strings**: The Supavisor connection strings are IPv4-compatible alternatives to direct connections
2. **Supabase Client Libraries**: These libraries are compatible with IPv4
3. **Dedicated IPv4 Add-On (Pro Plans+)**: For a guaranteed IPv4 and static database address for the direct connection, enable this paid add-on.
### Checking your network IPv6 support
You can check if your personal network is IPv6 compatible at https://test-ipv6.com.
### Checking platforms for IPv6 support:
The majority of services are IPv6 compatible. However, there are a few prominent ones that only accept IPv4 connections:
- [Retool](https://retool.com/)
- [Vercel](https://vercel.com/)
- [GitHub Actions](https://docs.github.com/en/actions)
- [Render](https://render.com/)
## Finding your database's IP address
Use an IP lookup website or this command (replace `<PROJECT_REF>`):
```sh
nslookup db.<PROJECT_REF>.supabase.co
```
## Identifying your connections
The pooler and direct connection strings can be found in the [project connect page](/dashboard/project/_?showConnect=true):
#### Direct connection
IPv6 unless IPv4 Add-On is enabled
```sh
# Example direct connection string
postgresql://postgres:[YOUR-PASSWORD]@db.ajrbwkcuthywfihaarmflo.supabase.co:5432/postgres
```
#### Supavisor in transaction mode (port 6543)
Always uses an IPv4 address
```sh
# Example transaction string
postgresql://postgres.ajrbwkcuthywddfihrmflo:[YOUR-PASSWORD]@aws-0-us-east-1.pooler.supabase.com:6543/postgres
```
#### Supavisor in session mode (port 5432)
Always uses an IPv4 address
```sh
# Example session string
postgresql://postgres.ajrbwkcuthywfddihrmflo:[YOUR-PASSWORD]@aws-0-us-east-1.pooler.supabase.com:5432/postgres
```
