cloudflares https://1.1.1.1/cdn-cgi/trace and https://1.0.0.1/cdn-cgi/trace are not returning the client ip anymore

[cchriso]

Describe the bug
I noticed my ddns updates are updated with a weird ip address and I had a look at the code - I saw that the cloudflare /cdn-cgi/trace endpoint are giving back a strange IP (104.18.0.0) and not my client ip as usual, so we have to find another way to get the current ip. I found that https://cloudflare.com/cdn-cgi/trace is still serving the correct client IP, I will submit a PR that fixes this probably today.
I was not able to find docs regarding a change to that endpoint from cloudflare. So maybe it is a fluke/hiccup and cloudflare will fix it

To Reproduce
Steps to reproduce the behavior:

1. Go to https://1.1.1.1/cdn-cgi/trace and see the ip for yourself

Expected behavior
that it returns the client ip

Additional context
I understand that this is a cloudflare issue, nonetheless the application is not working

[PhaineDev]

Same issue here. Everything pointing to: 104.18.0.0

10$ side bet new cloudflare interns forgot to forward the original clients' IP when changing some ingress balancer config 😂

Ran into this as well, as far as I know the cdn-cgi/trace endpoint is meant for debugging only and Cloudflare does not make any guarantees about what it returns. Would be more sensible to not rely on it at all

I've personally used https://api.ident.me, it's simple and privacy friendly

[darioackermann]

basically this one #203 with some variety of ifconfig.co, api.ipify.org , etc...

+1

IPv4 gives 104.18.0.0
IPv6 gives 2606:4700:7::

Just happened to me right now, lost all connections!

Is this addressed on a newer version? Or can I configure the endpoint to return the IP?

I personally love api.ipify.com and api64.ipify.com

Cloudflare already fixed it for me as of a minute ago. It was returning the same IP as you for about half an hour.

[Tarballwalf]

Can confirm. I was freaking out thinking I got blacklisted somehow

[cchriso]

True, now cloudflare fixed it. But nonetheless I think I will fork this repo and push my own docker images just to be sure in the future, I really want to be able to control where it gets my IP from and I think this repo in general is rather dead...

[Tarballwalf]

damn I was not even aware this project is basically dead. I've set this up years ago and it had just worked fine ¯_(ツ)_/¯

[allancoding]

Same thing append to me. I lost access to everything. Randomly fixed a couple minutes ago.

if the issue happens again you can use my image on dockerhub https://hub.docker.com/r/cchriso/cloudflare-ddns - here I resolve the IPs with the https://cloudflare.com/cdn-cgi/trace url, which worked when the issue arised with the IPs directly

I also will continue to work on the fork, so feel free to open new issues with suggestions. I for sure want to enable more IP resolvers like api.myip.com etc.
