Migrating Your DNS to the Cloud

“DNS is the Internet’s equivalent of a phone book,” said every DNS enthusiast ever.

Basically, there are a bunch of servers, called the root, that maintain domain names, like or, and translate them to IP addresses. This is primarily because computers or machines access websites based on IP addresses that are not as easy for people to remember as domain names. Easy enough, right?  So let’s take it an extra step.

Managed DNS is just that. A managed service (that’s us) for your DNS (that’s you), who is providing you fast, reliable, secure, and stable connections to your website or online content. Multitudes of companies trust Dyn to manage their DNS.

When talking to businesses, the number one fear we help folks overcome is switching to a new managed DNS network and provider while avoiding any downtime. If you have this fear, I have some great news. Moving your DNS to a managed DNS provider (again, that’s us) is easy and straightforward and you can accomplish it in just 3 easy steps, all while avoiding downtime:

  1. Create a zone for your domain.
    • Think of a “zone” as a container that holds all of your DNS records (A, AAAA, MX, TXT) for your domain. If your domain is named, the zone name will be
  2. Add your DNS records to your newly created zone.
    • You should be able to get a zone file in BIND or TinyDNS format from your current provider and import it directly into your account. The zone file is typically a text file that contains all of your DNS records in a specific format.
    • No zone file? No problem. Manually creating a zone file is pretty easy with our expert editor.
  3. Publish your zone update and prepare for launch!
    • Once you have verified your zone, click Publish. This will push (propagate) the newly created zone with all of its DNS records to our nameservers immediately.


Your customer account information will show what its assigned Dyn nameservers are. Next, go to your domain registrar (where you pay your yearly fee to own your domain name) and replace the existing nameservers with the new Dyn nameservers listed in your account.

Once this change is made, Dyn will answer any new DNS queries immediately. The DNS was designed to be cached out on the edge where it is used. This provides performance gains because you don’t have to go looking for answers you still have handy. As a result, you have to wait about 24 to 48 hours for the whole global edge of resolvers to clear out what they have in cache. To air on the conservative side, I recommend that you keep your zone active on your previous DNS provider for one week just in case any queries happen to reach your old provider. After a week, it’s safe to deactivate the account at the previous provider.

Why does this work so well for our customers?

We do this with a fully optimized IP anycast network. We work with companies like you every day to ensure a fast and reliable migration to our Managed DNS IP anycast network. Our IP anycast network is deployed on top of a global IP network, consisting of 18 POPs and connectivity from a varied mix of Tier 1 ISPs.

Within each data center, we distribute traffic to multiple data centers, providing global load balancing using the anycast routing technique. This network allows Dyn to offer its customers a world-renowned level of service and reliability.

We see, on average, folks who migrate to Dyn see immediate performance gains of upwards to 80% improvement to their domains latency and deviation.

Questions to ask yourself:

  • Are we using the right equipment to reduce DNS traversing?
  • What tactics are we implementing to reduce latency and increase revenue?
  • Who oversees our ability to optimize our online traffic?
  • How awesome would I look if I had Managed DNS with Dyn?
