How do I set up DNS with Cloudflare?

If you use Cloudflare to protect your website or app, Cloudflare DNS will be the name servers for your domain.

This is a crucial step, but it's often overlooked.

We're going to set up your Cloudflare DNS for your domain. For simplicity we'll skip over the process of creating accounts, but you will need an account for this.

Step 1. Create a Cloudflare Account To get started, go to the Cloudflare Website and sign up for a new account. This process will take you through a simple wizard to help you create an account. You will have to verify your email, so make sure you choose a good one. In this case, I chose:

Once you sign up, you'll be shown the dashboard. Head over to the tab called DNS.

This is where we set up our DNS. Click on the green Create DNS Record button.

Step 2. Choose a Record Type There are 3 types of records that you can add to Cloudflare. The first is A records. This is used to define the name of the website or application. The IP addresses in these records match what Cloudflare will return to visitors and should be correct.

Another type of record is a CNAME record. A CNAME will point the name of the website or application to a different site (ie www.example.com points to www.yoursite.com ).

There's another type of record, which is MX records. This is what you need for email service. Each email provider has a unique domain. When you get your email from Gmail, Hotmail, etc., those are all valid domains that Google, Hotmail, etc. Have assigned. So, if you get email from hotmail.com or gmail.com, these are valid records that define that domain.

The last option is a NS record. These are used to set up subdomains, like www.mysite. This records is what you'll use to create a subdomain on your website. We'll use ns.cloudflare.

How do I setup a reverse DNS server?

(BIND9, centOS5)

What is reverse DNS? How do I setup one? I need one to add a subdomain of some host I'm hosting on my webserver. What are the steps? Do I need to have it on my DNS server, or does it just need to be on the server that will host the www. And *myDomain (the subdomain)? And where should I start?
I've googled around and found a bunch of different explanations, but no one of them seem to be able to explain why I need one. :-p This is not what a Reverse DNS server does, but anyway: I assume that you are using a dynamic ip and want to resolve some IPs with a name instead of an IP? In this case, you do not need a DNS Server for this, as Windows comes with a DNS resolution mechanism built in, by using "Windows search". If you just have a static IP you would have to use some external DNS Server which could do all this, then it all comes down to configuring the server, no magic involved. If you would need to be able to resolve dynamic IPs to other than the one being pointed to, then you would need a more complicated (and thus, expensive) setup.

If you don't like how Windows works, you could use Windows Server as a DNS server instead.

How to set reverse DNS in Cloudflare?

When I log in to my Cloudflare IP address, I get this message.

Reverse dns is not set for this subdomain. See to add one.

I searched google and found that it should be set by editing the zonetransfer.cf file in the config folder, but that was not enabled and I couldn't figure out how to enable it. I've also contacted cloudflare help chat about this and they have told me that setting reverse DNS in the zonetransfer.cf file should enable it.

So does anyone know how to set reverse DNS for a Cloudflare IP address and is what the team said in the chat is accurate? If you go to the reverse DNS section in your Cloudflare account management dashboard. You will see where to add the new domain as if they were managing their own DNS. This is what you need to do.

Open the config tab (in the right side bar you will see this. You can change between config or dashboard).

Add the domain (eg mydomain.com) Update the A record for the IP addresses you want reverse DNS for the zone.

How to setup reverse proxy with Cloudflare?

We have just upgraded a web site from a free hosting company to a managed Cloudflare.

Com offering.

Now I have configured reverse proxy to work as below: Nginx/0.8.42 :
Server.
The above works as expected - it directs all traffic to the local application in my machine on Port 3000. When I try to open in browser by specifying URL with IP address instead of DNS or HTTP name, I get this error: ERRNAMENOTRESOLVED 302. How can I configure this so that traffic comes from Cloudflare without any special instructions for this new IP address? Try removing the "port" in your "listen" block, and also removing any "Port:" options. So the following block should not be present in your config: listen 80 ; # the default port, leave this as is. As your "listen" block already includes the ":30001" in the end, it doesn't make much sense. And as you use IPv6 on CloudFlare, it's probably best to remove any "::" too, because your application will only listen to the IPv6 interface if you remove it.
