Summary: IP Allow is a Neon Scale plan feature that blocks connections from any IP address not on an explicit allowlist. It supports individual addresses, ranges, and CIDR notation. Use it to enforce network-level access control beyond database credentials alone. Restrictions can be scoped to protected branches only, leaving other branches unrestricted, and are configured in project settings.

Limit database access to trusted IP addresses

Neon's IP Allow feature, available with the Neon Scale plan, ensures that only trusted IP addresses can connect to the project where your database resides, preventing unauthorized access and helping maintain overall data security. You can limit access to individual IP addresses, IP ranges, or IP addresses and ranges defined with CIDR notation.

You can configure IP Allow in your Neon project's settings. To get started, see Configure IP Allow.

If IP Allow is enabled on your project, add the following IP addresses to allow connections from Neon hosted services:

You can apply IP restrictions more precisely by designating specific branches in your Neon project as protected and enabling the Restrict IP access to protected branches only option. This will apply your IP allowlist to protected branches only with no IP restrictions on other branches in your project. Typically, the protected branches feature is used with branches that contain production or sensitive data. For step-by-step instructions, refer to our Protected Branches guide.

Tip: If you are an AWS user, Neon also supports a Private Networking feature, which enables connections to your Neon databases via AWS PrivateLink, bypassing the open internet entirely. See Private Networking.
