Overview

To route web traffic through the Cloudflare network, update the nameservers at your domain registrar to resolve your domain’s DNS with Cloudflare's nameservers. Updating your nameservers does not change where your website is hosted. Also, you can still use OpenDNS, Google DNS, etc for recursive DNS although Cloudflare recommends the 1.1.1.1 resolver.

To start:

1. Enter your domain at ICANN WHOIS field:

2. Log into the administrator account for your domain registrar.

3. Replace the current nameserver records in your registrar account with your domain’s Cloudflare nameservers. Allow up to 72 hours for nameserver changes to globally propagate.

Contact your registrar's support center for the most accurate information. See below for instructions on changing nameservers at popular registrars:

1and1	FlokiNET	Name.com
Blacknight	Gandi	NameCheap
BlueHost	GoDaddy	Network Solutions
DirectNIC	Google Domains	OVH
DNSMadeEasy	HostGator	Rackspace
Domain.com	HostMonster	Register
Dotster	Internetbs	Site5
DreamHost	iPage	Softlayer
EasyDNS	MediaTemple	Tucows
Enom	MelbourneIT	Yahoo!
Fast Domain	Moniker	Yola

4. Refresh the Cloudflare Overview app. If Complete your nameserver setup still appears, Perform the following steps:

Ensure the ICANN WHOIS Name Server output correctly spells the Cloudflare nameservers and confirm Cloudflare's nameservers are the only nameservers listed.
If theICANN WHOIS Name Server output is correct, click the Re-check now button in the Cloudflare Overview app.

5. If Complete your nameserver setup no longer appears in the Cloudflare Overview app, you have successfully updated your nameservers and your domain is active at Cloudflare.

Once your domain is active on Cloudflare, review our best practices for active Cloudflare domains.

If you run into issues, refer to our Troubleshooting FAQ for new Cloudflare customers.

Confirm traffic is proxied to Cloudflare

Some online tools such as GTmetrix don't recognize Cloudflare as a Content Delivery Network (CDN) because we don't operate like a traditional CDN. Instead, confirm your domain traffic actively proxies through Cloudflare by browsing to https://www.example.com/cdn-cgi/trace. Replace www.example.com with the domain and hostname proxied to Cloudflare. If proxied to Cloudflare, output similar to the following appears in the browser:

  fl=4f177
  h=www.example.com
  ip=2001:1900:2200:7525:749f:9ed1:444c:80b4
  ts=1562191016.292
  visit_scheme=https
  uag=Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_6) AppleWebKit/537.36 (KHTML,
  like Gecko) Chrome/74.0.3729.157 Safari/537.36
  colo=SJC
  http=http/2
  loc=US
  tls=TLSv1.3
  sni=plaintext
  warp=off

If you don't observe similar output:

Confirm your DNS record is orange-clouded in the Cloudflare DNS app,
Enter your domain at ICANN WHOIS to confirm the Name Servers only list Cloudflare nameservers for your domain, or
Contact Cloudflare Support.
