# Setting up Heroku DNS using cloudflare

Setting up Heroku DNS using cloudlfare

Lots of folks know [cloudflare](https://www.cloudflare.com/) for the DDoS
protection, rate limiting etc services it provides. Here at BigBinary, we also
use Cloudflare for DNS management.

DNS management is a free service by Cloudflare. However, on first glance, it
might not appear that it's a free service. Once we add a site, then we see a
screen like this. Here, we need to remember to scroll down to see the free
option.

Now let's see how we can map the DNS settings from Heroku to Cloudflare. We will
look at both a standard domain name and then we will take a look at a wildcard
domain name.

### Standard domain name

We are hosting [GitEmit](https://www.gitemit.com/) using Heroku. We are letting
Heroku manages the SSL for this domain.

After setting up domains in Heroku, here is what we see.

In Cloudflare, we can set it up using two CNAMEs. It looks like this.

### Wild card domain name

We are hosting [NeetoChat](https://www.neeto.com/neetochat/) application using
Heroku.

Since it's a wild card domain, we had to
[generate the certificates](https://www.bigbinary.com/blog/wild-card-ssl-on-heroku)
ourselves.

After setting up domains in Heroku, here is what we see.

In Cloudflar,e we can set it up using three CNAMEs. It looks like this.
