Probe IP allowlists for your firewall

Pull the egress IPs of the whole probe fleet as plain text or JSON, no account required.

/ips-v4, /ips-v6 and /ips.json return the current fleet, in the style of the Cloudflare lists.
Built from active locations and the address each probe last reported, so the list follows the fleet instead of going stale.
No authentication, so a firewall rule or a config management job can fetch it directly.
