Self-host DNS for it? Yea, you can create NS Records in Cloudflare to delegate the subdomain to your own nameservers.
If you just mean a normal web server (a/aaaa/cname), then yea you can just create those records unproxied

Thanks, I think the first is what I'm after. My domain is hosted on Cloudflare, but I want to self-host a subdomain from my own server at home. So a NS record is what I would want to use here?

ChaikaOP•7/12/23, 5:59 PM

What do you mean "self-host a subdomain"? Do you want to host the DNS for it (like with bind or powerdns), or do you want to just serve a non-proxied (i.e straight to your origin, not through Cloudflare) Web Server/other type of server?

Hmm, that's a good question lol. Currently my root website.com is proxied through Cloudflare to my Linode VPS. I was hoping to point (hopefully proxied) to my self-hosted server for the subdomain.com website. I believe pfSense has a Dynamic DDNS function for Cloudflare to do this but I'm not entirely sure how to plumb it all to get it working. If that makes sense?

ChaikaOP•7/12/23, 6:09 PM

That makes sense yea, your initial wording made me think you were trying to do something different.
Cloudflare offers something called Cloudflare Tunnels, which you can install on your self-hosted server, they establish an outbound connection to Cloudflare, and then proxy requests to your local web server. They are very handy for self-hosting, they don't require any port forwarding or dynamic dns, they don't care at all if your IP changes since they connect outbound: https://developers.cloudflare.com/cloudflare-one/connections/connect-apps/install-and-setup/tunnel-guide/remote/

Alternatively, you could use something like dynamic dns utlity with Cloudflare support and port forward either proxied or unproxied

Yeah, I'm sorry. I'm a newb at all of this so my wording will be problematic

fleabeard•7/12/23, 6:16 PM

I guess what I need is the temporary IPv4 Address. I think it used to be 1.1.1.11.1.1.1 but was changed. Do you happen to know what that would be?

https://developers.cloudflare.com/dns/troubleshooting/faq/#what-ip-should-i-use-for-parked-domain--redirect-only--originless-setup you can use 192.0.2.0

Cheers!

is it possible to purchase / register domains via API for non enterprise customers?

Erisa•7/12/23, 7:04 PM

No, it's not

Cyb3r-Jak3•7/12/23, 9:44 PM

You just delete the application covering the URL

Cyb3r-Jak3•7/12/23, 9:44 PM

There is a free plan for up to 50 users

Cyb3r-Jak3•7/12/23, 9:44 PM

How did you set it up?

Cyb3r-Jak3•7/12/23, 9:46 PM

You can put in payment info for it then delete it. It isn't used unless you go over 50 users

Unsmart•7/12/23, 9:47 PM

You might be able to use the API otherwise yeah you might have to enter in the card to use it

is this code irregular? It gives an error

"message": "firewallrules.api.malformed_request_body"

the expression rule is alright, copied it myself from a working domain

btw i used php

ChaikaOP•7/13/23, 1:02 PM

probably the easiest way would be to find all of the ASNs/Providers they use and block/challenge them, looks like they use SurfEasy under the hood, generally more trouble then it's worth imo

BBUTTΞRKΞKS1000 Ok maybe it wont show in the mobile view

ChaikaOP•7/13/23, 1:06 PM

it should, although it's pretty unusable unless you're on a very wide phone/tablet or something. You don't see the button, or it doesn't load?

Does cloudflare automatically add CAA records for free Universal SSL customers? https://developers.cloudflare.com/ssl/edge-certificates/caa-records/

Add CAA records · Cloudflare SSL/TLS docs

A Certificate Authority Authorization (CAA) DNS record specifies which certificate authorities (CAs) are allowed to issue certificates for a domain. …

mystiquewolf•7/13/23, 5:46 PM

i don't see such added. How to prevent others CAs than the ones that Cloudflare uses?

mystiquewolf•7/13/23, 5:48 PM

I mean i see that they won't appear in the dashbard, but dig doesn't show CAA records too. AFAIU Cloudflare adds it's own CAA records if you try to add at least one custom CAA. But what if i don't want a custom one but only the Cloudflare ones?

This has not been well thought feature
