Different nameservers for different zones

Hi, since Cloudflare name servers are a way to uniquely identify an account, and it is possible to identify all domains under the account by simply seeing which domains have the same set of 2 name servers, is it possible to switch up the name servers for each new zone for enhanced privacy?

I have implemented SSR (Server-Side Rendering) in React, but it’s not working properly because of Cl

I’ve set up a staging domain; here’s the link: https://staging.sportsfinda.com/ Our React project was initially running through a build setup, but now we’ve created a Node server, implemented server-side rendering, and are running the project using PM2. When we remove Cloudflare, everything works properly. However, when we enable Cloudflare, the meta URLs don’t display correctly when sharing on social sites like Basecamp, WhatsApp, Instagram, etc. I have implemented SSR (Server-Side Rendering) in React, but it’s not working properly because of Cloudflare. Could you please help with this?...

Cloudflare IPV6 behaviour

How does Cloudflare behave in situations where a user supports both Ipv4 and Ipv6? I've read https://developers.cloudflare.com/network/ipv6-compatibility/ but the wording makes me a bit unsure about if it is referring about doing Ipv6 to the upstream servers or if it will prefer to use Ipv4 if a client has dualstack support.

SSH configured tunnel

Having trouble getting ssh to work through I've set up the config, and CNAME in cloudflare with 'cloudflared tunnel run <tunnel-name>' and in DNS dashboard verified CNAME entry '<tunnel-name>.cfargotunnel.com' is present. If I attempt ssh [email protected] it goes to timeout. In DNS-analyics, I see the queries there, but nothing in security event logs. So I'm not entierly sure how to proceed or debug since every think, as far as i can see, its green lights...

Origin Rules for reverse proxy

I’m setting up a reverse proxy using Cloudflare origin rules and could use some help troubleshooting. The goal is to have two rules in place: 1. Primary Rule: Requests to app.example.com/api/endpoint* (including any query strings) should route to app.otherdomain.com/api/endpoint, passing along any query string parameters....

cloudflare proxy doesnt stream responses

i have a sveltekit app hosted on fly.io, using cloudflare proxy/cdn for caching. with sveltekit you can stream data for your page so that slow loading data can be continually loaded without slowing the page down. when using the cloudflare proxy, that isnt working for me....

What on earth does `sliver` in `cdn-cgi/trace` means?

For example, if one does a curl https://cloudflare.com/cdn-cgi/trace, most fields are pretty self-explanatory. However, I could not find any references to the sliver field means apart from some Cloudflare Forums posts that doesn't exactly explain it either. Just curious how it can sometimes be none and after you refresh it can become something like 010-hkg08

My CNAME records are not showing up on dns checkers

I already added it on cloudflare though and everything else is fully propagated. That is the A records, Nameserver and mx records. Also the cname records are not proxies on cloudflare. Does anyone know why this is happening?

I'm trying to connect my Cloudflare Domain to my Wordpress site but my problem is Cloudflare requirres an IPv4 address, while Wordpress on has named servers.
