Moving DNS

Part 1: Moving DNS Registrar

I bought my domains quite a while ago via GoDaddy, but I had my DNS servers at Linode as that’s where the VMs were I used. Linode have an easy-to-use GUI and a well-working API (important for Let’s Encrypt certificates via acme.sh). Life was good. when it was renewal time and GoDaddy’s prices increased quite a bit, I moved the registrar from GoDaddy to AWS: it was actually cheaper than GoDaddy and there are zero attempts to sell more things to me I don’t need.

Recently I started to look at Cloudflare Workers when I saw that CF is also a registrar. And it’s a rather special one:

Cloudflare Registrar securely registers and manages your domain names with transparent, no-markup pricing that eliminates surprise renewal fees and hidden add-on charges. You pay what we pay — you won’t find better value.

See https://www.cloudflare.com/products/registrar/

Well, that sold me. So I moved from AWS to CF for one of my 2 domains, and it was done in about 30min. Most of that time I was waiting for an email from AWS on my wrong email account. It probably could have been done within 5 minutes.

Moral of the story: Don’t be afraid of moving your DNS registrar.

Part 2: Moving DNS Server

While moving the registrar is a non-event with no outages whatsoever, moving DNS servers for a zone is more worrisome as there can be outages for your domain. Cloudflare makes it quite easy to move a zone to them: add your zone to CF, and they’ll give you 2 DNS servers which you need to update in your registrar’s zone info. Then CF will shortly later copy the zone information (mostly) over.

Few rarely used entries were not copied for some reasons. Add those missing ones. Keep the old zone active for a while (look at your TTL time in the SOA record).

And that’s it.

The most interesting part of Cloudfront is that their DNS server (usually) proxies traffic through their servers before contacting my server. And they cache the data. So theoretically that might make my web page faster. It now got some DDoS protection, I can turn on firewalls, do HTTP/3, and learn where traffic comes from. Like this:

I can understand that plenty requests come from US. That’s where Google & Friends got their crawlers and my blog is in English, but why France?

The main reason I moved DNS servers is that now I can use CF Workers using my domains. And that works just fine. An unintended side-effect of the DNS servers move is that Let’s Encrypt certificates via acme.sh now take seconds instead of (15) minutes to renew. That’s 2 wins for me!

Now let me see what shenanigans I can do with those CF Workers ☺
