I am new here.
I have my domain registered with domain.com but I use it as external domain with IONOS as a server provider. That means I have domain Namerservers pointed to IONOS (ns1045xxxxxxcom, etc)
Now configuring Cloudflare I changed NS on domain.com as specified in instructions (clydecloudflarexxx, etc)
My question is should I add old IONOS nameservers to cloudflare DNS settings? or it is not needed?
Another question is that after checking webpagetest with active domain it does not show that it is using CDN, what can be the problem?
