I own a domain at 1&1, and recently switched to CloudFlare CDN. I have some subdomains hosted at the minimal web space provided by 1&1.

1&1 domains and subdomains are configured to use CloudFlare name servers from the settings under 1&1 control panel.

When I go to CloudFlare DNS settings, I am not sure what to specify in A or CNAME record for the subdomains hosted by 1&1. I have gone through 1&1 help and settings, but not able to find this information. I used ns-es.1and1-dns.es and 1and1.es as CNAME, but didn't work.

Previously, CloudFlare detected IP for A records, but 1&1 recently switched web servers and the subdomains have stopped working.

  • In short, domain and web hosting are both provided by **1&1**, but I am using **CloudFlare** name servers, and can't figure out `CNAME` or `IP` for [_the included subdomain in 1&1 hosting package_](http://help.1and1.com/domains-c36931/transfer-domains-c79823/to-1and1-c37567/add-an-external-domain-that-uses-your-name-server-a713215.html); a problem others have [stumbled over too](https://www.sitepoint.com/community/t/pointing-external-domain-to-1and1-webspace/7276)! – M K May 02 '16 at 21:41

When you create a root domain at 1&1, another domain is created alongside of the format s12345678.onlinehome.us or s12345678.mialojamiento.es etc. This second domain acts as CNAME record for the root domain or any subdomains, when using a third party name server.
