Detecting the real IP of a Cloudflare'd Mastodon instance

Detecting the real IP of a Cloudflare'd Mastodon instance

NB: This will not work for instances that proxy outgoing requests!

Reading the docs

I wanted to find a way to detect the real IP address of a Mastodon/Pleroma/Misskey/etc instance hosted behind Cloudflare. How to do that? Well, it's federated, which means I can probably get it to send a request to a server of mine! And how to do that? I tried reading the ActivityPub spec. The following caught my attention:

Servers should not trust client submitted content, and federated servers also should not trust content received from a server other than the content's origin without some form of verification.

Simple Github -> Discord webhook

Step 1 - Make a Discord Webhook

  1. Find the Discord channel in which you would like to send commits and other updates

  2. In the settings for that channel, find the Webhooks option and create a new webhook. Note: Do NOT give this URL out to the public. Anyone or service can post messages to this channel, without even needing to be in the server. Keep it safe! WebhookDiscord

Step 2 - Set up the webhook on Github
