Can I point to another NS while using Cloudflare?

I want to point my subdomain to another NS while using Cloudflare, is there a way to not modify my original Cloudflare NS and point it to other NS?

You can delegate for a subdomain (not the apex domain). Just add NS records for the subdomain to your Cloudflare DNS.

like this?


I’ve tried it but it won’t work

That’s correct. What is the domain?

my domain: freehost.firstnewblogforfeng20221225.cn.eu.org
I verified this domain firstnewblogforfeng20221225.cn.eu.org on cloudflare
ns:
ns1.byte.org
ns2.byte.org
ns3.byte.org
ns4.byte.org

I got this when directly access to my site 域名 freehost.firstnewblogforfeng20221225.cn.eu.org 可能已经被 DNS 污染,如果域名为本机域名,请解析为非回环 IP。

The namserver delegation is returned by Cloudflare, but ns1.byte.org, etc, don’t resolve. Do you mean ns1.byet.org? (If so, it’s not resolving for your subdomain).
