Closes DOCS-1087 <img width="1493" height="688" alt="Screenshot 2026-06-30 at 4 50 52 PM" src="https://github.com/user-attachments/assets/39267c8a-befb-4419-8fa8-4e987f82781e" /> ## I have read the [CONTRIBUTING.md](https://github.com/supabase/supabase/blob/master/CONTRIBUTING.md) file. YES ## Problem The Network Restrictions docs contain an incorrect curl example that, when followed, restricts the entire database instead of adding only the specified IP/CIDR — causing production outages for users. ## Solution Fix the incorrect curl command in the Network Restrictions docs so that it correctly adds only the specified CIDR rather than restricting the entire database. This PR solves the problem by adding an `--append` CLI procedure. Additionally, the document is improved: - All procedures are put in procedure format for easier readability and clear action steps - Wording is simpler - Headers follow convention - A "This topic..." intro paragraph is added ## Tophatting 1. Go to the preview link at `/docs/guides/platform/network-restrictions`. 2. Verify that the new `--append` section corrects the original issue. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Documentation** * Reworked the network restrictions guide into clearer “dashboard” and “CLI” setup flows. * Expanded the intro with IPv4/IPv6 CIDR allowlisting guidance, including exceptions for IPv6 migration extensions and when the IPv4 add-on is installed. * Updated the CLI instructions with structured examples for checking, replacing, appending, and fully removing restrictions (including the “never applied” case when allowed lists are empty). * Clarified scope/limitations: restrictions apply to Postgres and its pooler (not HTTPS APIs or client libraries), and enabling restrictions blocks Edge Function direct database access. <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Co-authored-by: Andrew Valleteau <avallete@users.noreply.github.com> Co-authored-by: Jeremias Menichelli <jmenichelli@gmail.com>
