Can we add a exception repo when enabling IP whitelisting

We’re facing an issue where enabling the IP allowlist causes our Vercel deployments to fail. These deployments are triggered by push events in the repository.

The challenge is that Vercel’s servers don’t have static IPs that we can whitelist.

What is the solution to this??

not very sure of your situation but these might be the workarounds :

1. use GitHub Apps with Token Authentication

   • Instead of relying on webhook delivery directly, connect Vercel via a GitHub App or deploy hook.
   • GitHub Apps authenticate with tokens, which bypass IP allowlist restrictions.

2. disable the Org-wide Allowlist ( not ideal, weaker security )

3. move the Repo

   • Host the repo that triggers Vercel outside the locked-down org (e.g., in a personal or non-restricted org).
   • This avoids the IP enforcement, while keeping sensitive repos protected.

4. Hybrid Setup

   • Keep allowlisting enabled for critical repos.
   • Use a separate org or mirror repo for CI/CD integrations like Vercel.

The IP allowlist feature works well when your deployment service has static IPs, but Vercel doesn’t provide a fixed IP range that you can whitelist. That’s why deployments fail when the allowlist is enabled.

Possible solutions:

Use a GitHub App / Deploy Key instead of push-based webhooks → This way, Vercel can pull directly from your repo using an access token, without depending on IP whitelisting.

Use GitHub Actions → Set up a workflow in GitHub Actions to build and deploy to Vercel. Since Actions run within GitHub’s network, they won’t be blocked by the IP allowlist.

Disable IP allowlist for GitHub Apps → In your org security settings, you can allow specific GitHub Apps (like Vercel) to bypass the allowlist.

Here’s GitHub’s doc on this: Managing allowed IP addresses for your organization
.

The recommended approach is usually #2 (GitHub Actions → Vercel), since it avoids the IP issue entirely. 🚀

This is working for us.

Thanks for the idea 👍
