Best Free DNS Hosting Providers

If you are in the process of building or expanding your website, choosing a high-quality DNS host is like getting a new best friend! You get increased reliability, speed, security, and redundancy.

There is nothing worse for visitors than when your website is down. However, with the rise of DDoS (Distributed Denial of Service) attacks where a web service is overwhelmed with so many requests that it collapses under the load, this danger is ever-present!

Using a high-quality DNS hosting provider is very important for the redundancy of your website. Moreover, in cases of DDoS attacks, infrastructure failures, or configuration errors, a single dedicated DNS server is not enough. You need multiple DNS providers on different networks to ensure DNS availability and reduce the risk of DNS downtime.

DNS hosting comes in different packages and options. Most DNS hosting providers charge for their services, but some great providers are free.

We have prepared this article with the best free DNS hosting providers for you to get a better overview and choose that best suits your needs and expectations. Moreover, by selecting DNS hosting providers we have listed, you can set up multiple DNS providers to eliminate the single point of failure.

However, before we start with the hosting providers and their information, we would like to say a few words about the important factors you should look for when choosing a DNS host.

What is DNS?

DNS, which stands for domain name system, is an Internet service that translates domain names into IP addresses. For example, when you visit KeyCDN.com and type in the address bar, 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. A DNS server maintains a directory of domain names and translates them into IPs, so all you have to do is type KeyCDN.com in your search, rather than a complicated long string of numbers. So you can think of a DNS server as a phone book for the Internet.

Why reliable DNS hosting is important

Choosing a reliable DNS hosting provider is critical because it can affect everything from the redundancy of your website, speed, and even security.

Redundancy

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

A common approach is configuring 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, suppose a lookup fails and times out to your first DNS server. In that case, it queries the next DNS server until the correct IP address is returned, or it cannot resolve, as seen in the infamous "This webpage is not available" error below.

ISPs cache DNS, however, so if your first provider goes down, it will still try to query the first DNS server for a while before querying for the second one. A quick fix is simply by temporarily changing the TTL setting for the DNS record and routing 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 your ISP will have the DNS cached, and users might not even notice if your DNS provider goes down for a short period. 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 less latency between the DNS lookup and TTFB. You can test the DNS lookup time and TTFB with a website speed test tool.

Like 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 setting a longer TTL means fewer queries to your DNS servers.
