So, if an Injection-Info header contains an IPv6 address (e.g.
“2a01:4f8:c0c:2f94::1”), the regex will not match it correctly.

1. What happens if the regex doesn't match?
2. How do you set a reverse DNS name for your IPv6 IP address with Hetzner?
3. What happens when the IPv6 address of your peer has a reverse DNS name?
