Subdomain in 1&1 with cdn of cloudflare

Hello,

I have 1&1, dome well with the dns propagation.

But none of the subdomains are working.

1and1 says the subdomain must contain 1&1 dns. And if I want cloudflare dns on the subdomains I need to host the subdomain in cloudflare.

How do I solve it?

You need to add a DNS record for ‘reserves’. It might have to be an “A” record if you know the IP address at 1&1, or it may have to be a CNAME pointing to something at 1&1.

If there’s a DNS page at 1&1 with hostname records, that should tell you what you should add for ‘reserves’ at Cloudflare DNS.

I don’t understand quite well.

When I add the cloudflare dns for the domain, 1&1 automatically changes the subdamain dns from the previous 1and1 dns to the cloudflare dns, there is , as far a I know, a way to put a specific dns for the subdomain. If you change the domain dns, the subdomain is the same dns…

and:

1and1 says the subdomain must contain 1&1 dns. And if I want cloudflare dns on the subdomains I need to host the subdomain in cloudflare.

You can try to add NS records for that subdomain that point to 1&1:
