10 Best Free DNS Hosting Providers

free dns hosting providers
With the rise of distributed denial-of-service (DDoS) attacks using a high-quality DNS hosting provider is very important to the redundancy of your website. There is nothing worse for visitors than your website being inaccessible. Check out these 10 free DNS hosting providers you can use to implement a multiple DNS provider setups and get rid of that single point of failure.

What is DNS?
DNS, which stands for domain name system, is an Internet service that translates domains names into IP addresses. For example, when you visit KeyCDN.com 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
Choosing a reliable DNS hosting provider is critical because it can affect everything from the redundancy of your website, speed, and even security.

If you are running a business, you should never have one single point of failure. DNS hosting providers do allow you to configure secondary nameservers, but then you are assuming 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 all of the sudden 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 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.

Oddly enough we encountered this error to a 3rd party website while writing this article. So DNS services definitely go down!

ISPs do cache DNS however 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 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.

According to Kaspersky in Q1 2015, 23,095 DDoS attacks were reported, targeting web resources in 76 countries. DDoS, or 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.

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.
