I am trying to delegate an NS to cloudlfare.
Let’s say I have a . b . com and I want to add an NS to use cloudflare dns under a . b . com
The idea is to manage anything to the left, like x . a . b . com using cloudflare free tier account.
Cloudflare is asking for a whole domain, and I don’t find any way to tell it to manage a . b . com, it looks it wants b.com
Edit: I added spaces between the dots since the forun takes them as “links”.
