FAQ & A

Name Server & Activation Questions

My name servers have not changed, but I made the change. Why not?

Not an active zone. Why?

  1. You changed your name servers with your hosting provider, not with your Domain Registrar
  2. There is a typo in your name servers
  3. The change is starting to propagate
  4. DNSSEC is active on the domain and the name server change will not take effect until it is removed
  5. You changed your name servers in cpanel, not at your registrar
  6. Your name servers were set properly, but you moved your domain to Cloudflare Registrar and your former registrar reverted to the old name servers on your way out the door
  7. You changed your name servers to Cloudflare, but you did not +Add zone to Cloudflare
  8. There is a hold with your domain that prevents changes from taking effect

Name Server Change Questions

Where do I change my name servers?

  1. At your domain registrar.
  2. If you’ve reviewed the list of popular domain registrars and don’t see yours listed or you don’t know your domain registrar, do an ICANN search to identify the registrar.
  3. You added your name servers as DNS records to the DNS tab of the Cloudflare dashboard. This is not correct, you need to change the name servers from those provided by your domain registrar to those provided by Cloudflare.
  4. You added your Cloudflare name servers properly at your registrar but have left one or more of your old name servers in place.

Orange & Grey Cloud Questions

What do orange & grey clouds mean on the DNS tab?

How do I orange cloud a DNS record?

What DNS records should have an orange cloud?

  1. A :orange: means your web traffic is running through Cloudflare making your site faster, safer, and smarter. A :grey: your web traffic not running through Cloudflare.
  2. Click an :orange: to turn it :grey: and click a :grey: to turn it :orange:.
  3. Only A and CNAME over web traffic ports (such as 80 and 443) records have the option to be powered by Cloudflare, meaning that only A, AAAA, and CNAME records have the option of an orange cloud.
  4. However, not all A, AAAA, and CNAME records are appropriate to pass through Cloudflare. Cloudflare makes suggestions for which records should be orange, but you can easily change this by clicking on the cloud.
  5. To decide which records pass through the Cloudflare network, you need to understand what type of content appears on that subdomain.
  6. You should enable Cloudflare for any subdomain that gets web traffic.
  7. You should not enable :orange: Cloudflare for subdomains that handle non-web traffic, such as mail, ftp, and ssh. These types of records should be marked by a :grey:.
