What is DNS?

N ot everyone knows what DNS stands for or why it’s an important aspect of their website. DNS stands for Domain Name System.

DNS, is an Internet service that translates domains names into IP addresses. For example, when you visit FastWeb.Host it must look up the corresponding IP address to that hostname behind the scenes. This query is performed by a Domain Name Server (DNS server) or servers nearby that have been assigned responsibility for that hostname. You can think of a DNS server as a phone book for the internet. A DNS server maintains a directory of domain names and translates them to IPs.

Why Reliable DNS Hosting is Important

With the rise of distributed denial-of-service (DDoS) attacks using a high-quality DNS hosting provider is very important to the redundancy, speed and even security of your website. There is nothing worse for visitors than your website being inaccessible. Therefore you need to choose a reliable DNS hosting provider.

Redundancy

If you are running a business, you should never have one single point of failure. Although DNS hosting providers allow you to configure secondary nameservers, you are then assuming that all of their services won’t be affected, ever. It is like storing a backup of your computer files on an external hard drive in your house. There could be a fire and all of the sudden you have lost both your computer and external hard drive, so all your files are now gone. Just as it is important to store backups offsite, it can also be beneficial to use multiple DNS providers.

A common approach is to configure one of the DNS providers as primary and the other as secondary, slaved to the primary provider. This means that your Zones records are synchronized from the primary to the secondary. For example, if a lookup fails and times out to your first DNS server it queries the next DNS server until the correct IP address is returned, or it is unable to resolve as seen in the infamous “This webpage is not available” error below.

Keep in mind that ISPs do cache DNS, which means if your first provider goes down it will still try to query the first DNS server for a period of time before querying for the second one. A quick way to fix this is simply by temporarily changing the TTL (time to live) setting for the DNS record, and route your traffic to the second DNS server until the outage is fixed.

In general practice, it is better to keep a longer TTL for DNS records because this means your ISP will have the DNS cached, and users might not even notice if your DNS provider goes down for a short period of time. For example, if your TTL record is set to a week on Monday, and your DNS provider is down from Monday night through Thursday, your users will not see any downtime due to your ISP caching the DNS.

Speed

Speed also plays a role with DNS. Using a fast DNS hosting provider ensures there is less latency between the DNS lookup and TTFB. You can test the DNS lookup time and TTFB with a website speed test tool.

Just like with content delivery networks, DNS hosting providers also have multiple POPs. In general, the more locations, the better as this means there will more likely be a DNS server closer to the visitor, decreasing the lookup time. But remember, ISPs also cache the DNS so by setting a longer TTL it means fewer queries to your DNS servers.

Security

According to a recent Akamai report DDoS attacks are getting more and more sophisticated, with advanced bots leading the way. Distributed Denial-of-Service, is a type of DOS attack in which it attempts to make a machine or network resource unavailable. DDoS attacks usually involve more than one-and often thousands-of unique IP addresses and often spoof DNS queries.

This is where having multiple DNS providers is vital. Read about what the Canopy.co team learned when a DDoS attack took out their DNS provider.

The Domain Name Server (DNS) is the Achilles heel of the Web. The important thing is that it’s managed responsibly.

Some free DNS hosting providers are equipped with features such as firewall policies, rate limiting, filtering, and blocking that can help mitigate and prevent DDoS attacks. And of course having multiple DNS providers means that if one is taken down from a DDos attack you can always resort to your secondary.

With so many options out there it’s normal to ask yourself

Who is the best free DNS hosting provider for 2019

We personally use and recommend CloudFlare since it’s among the fastest but they have so many other features that makes them really stand out. They are 100% free for unlimited domains, they have by far the biggest network of PoPs so we have a preference in their service overall.

Let’s look at the numbers

Who offers the best free DNS? Who has the least DNS lookup speed? Is free DNS hosting as good as paid DNS hosting? As you can see below a majority of the free DNS providers we mentioned above are competing neck and neck with the speeds of premium providers.

2019 DNS Speed Comparison Report from Solve DNS

2019 DNS Speed Comparison Report from Solve DNS (both Free and Paid Services)

As you can see in the report NS1 really dominates the market in terms of speed with CloudFlare actually being 2nd from our list in terms of speed. Everything less than 10 milliseconds is great for DNS lookups especially for free ones!

If you look at last year reports or the year before that, you’ll notice that NS1 wasn’t always the fastest, that means they are committed in their service and continuously improve and invest in their platform. This brought them at the top of the list for now.

Final Notes

The availability of free DNS hosting services and providers is a great way to keep your costs low, something that will be very appealing in small – medium businesses who are on a tight budget.

Basically with CloudFlare (and others) offering so much even on their completely free plan means that if you ever have a need for a paid service, your company will be so big that you won’t even notice the cost… 😉
