Have a subdomain whoose only purpose is Cloudflare redirecting before it even hits the origin?
Change the DNS record to a AAAA
record that points to 100::
and, obviously, make sure it’s CF Proxied (orange cloud!). It now points to nothing but Cloudflare Redirect rules will still work. Cloudflare will automatically make a corresponding A
record for IPv4.
Cheers Lewis. Apparently 100::
is the official recommended IP for this purpose.
