I found a few older posts on using the dummy IP of 220.127.116.11 in order to make a Page Rule for a permanent redirect, but I need to double check officially that this is still the case so I am not having hanging IPs. If so, where is there an official list of Dummy IPs for Cloudflare? I am just concerned about the security implications of having an open IP that I am not fully confirmed on the official usage, this is my first experience with “dummy IPs”. Any additional context would be great, thanks!
You can find a list of reserved IP addresses that are not assigned publicly here: Special IP Address Ranges and When to Use Them | Auvik
18.104.22.168 is not one of those though.
192.0.2.1 is what I usually see recommended, and it is also on that list of reserved IPs.
Where did you stumble upon the 1.2.3 version?
Gotcha, okay so are these “special IP ranges” not specific to Cloudflare and a general reserved IP address range designated by the IETF.
I found that IP here:
But I am glad I followed my intuition and not trusting some random blog!
Thanks, I will use “192.0.2.1” as a Dummy IP to point my records to so I can redirect with page rules on Cloudflare
Instead of a proxied A record with a
TEST-NET-1 IP, I am now partial to creating a proxied AAAA record with the Discard-Only prefix of
100:. I like that it is nigh impossible to mistake it for anything else.
