rembDedicated IPv4 Address for Ingress
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.
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:#
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.
- 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.
You can also manage the IPv4 add-on using the Management API:
1# Get your access token from https://supabase.com/dashboard/account/tokens2export SUPABASE_ACCESS_TOKEN="your-access-token"3export PROJECT_REF="your-project-ref"45# Get current IPv4 add-on status6curl -X GET "https://api.supabase.com/v1/projects/$PROJECT_REF/billing/addons" \7 -H "Authorization: Bearer $SUPABASE_ACCESS_TOKEN"89# Enable IPv4 add-on10curl -X PATCH "https://api.supabase.com/v1/projects/$PROJECT_REF/billing/addons" \11 -H "Authorization: Bearer $SUPABASE_ACCESS_TOKEN" \12 -H "Content-Type: application/json" \13 -d '{14 "addon_variant": "ipv4_default",15 "addon_type": "ipv4"16 }'1718# Disable IPv4 add-on19curl -X DELETE "https://api.supabase.com/v1/projects/$PROJECT_REF/billing/addons/ipv4_default" \20 -H "Authorization: Bearer $SUPABASE_ACCESS_TOKEN"
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.
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:
- Supavisor Connection Strings: The Supavisor connection strings are IPv4-compatible alternatives to direct connections
- Supabase Client Libraries: These libraries are compatible with IPv4
- 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:
Finding your database's IP address#
Use an IP lookup website or this command (replace <PROJECT_REF>):
1nslookup db.<PROJECT_REF>.supabase.co
Identifying your connections#
The pooler and direct connection strings can be found in the project connect page:
Direct connection#
IPv6 unless IPv4 Add-On is enabled

Supavisor in transaction mode (port 6543)#
Always uses an IPv4 address
