Domain name system (DNS) (also sometimes referred to as domain name service or domain name servers) is an essential part of not only what makes the World Wide Web work, but most parts of the Internet. In essence, DNS is used to translate hostnames into actual IP addresses, routing mail to the right servers, etc. As fast and reliable DNS is quite essential I have here compiled a list of 10 free DNS providers that have proved to offer stable, fast and interesting DNS free of charge. Most the following providers will be able to compete with DNS provided by hosting providers and paid services. Actually, some of the providers listed below are among the most popular DNS providers also offering a limited free plan of their paid plans. You can get more information about the performance of most major DNS providers at DNSPerf.
Please post comments with your experiences with free DNS providers, corrections, and questions.
The following list is in no particular order as it ‘s hard to rank the free DNS providers from best to worst because they provide different types of DNS service. For example, Hurricane Electric (HE.net) provides a stable, fast, and no limits service, but have a simple interface with limited features making it bothersome if you manage several domains and need to make frequent updates. Other free DNS providers offer more features but have different types of limitations, so the best provider depends on your specific needs.
Hurricane Electric is a top class free DNS provider that both can be used for hobby and production domains. They are limited to 50 domains. They provide both primary and secondary DNS.

The well-known proxy and CDN provider CloudFlare is also offering free DNS on a solid anycast network. On special feature is CloudFlares IPv6 Gateway included in the free plan. In case your server only can be accessed through IPv6 CloudFlare provides a gateway and makes your server accessible through IPv4 as well. This does have some limitations in relation to actually having a dedicated static IPv4, but for serving web pages, etc. this will fit common needs. Besides regular DNS service, it’s also possible to add a line of additional services such as proxy, caching of some static files, DNSSEC, and SSL. They offer service for unlimited domains.

DNS4.pro is offering an easy to setup and use DNS solution. They are limited to 10 domains.
Well established and known for providing a high-quality DNS product. They offer unlimited domains. A nice feature is that if you use FreeDNS for primary DNS, they allow users to add additional external secondary name severs. Part of the idea behind FreeDNS is to allow people with no domain to create a free subdomain of domains using primary DNS from FreeDNS (it is possible to pay a fee to avoid this). While the idea of sharing is a good and useful it will also be a major concern for many domain owners as they partly lose control of how their domain is used and exposed. This is the main reason why I not personally use FreeDNS for primary DNS for any of my domains.

GeoScaling is a relatively new DNS provider. What makes them interesting is that they are offering what they call smart subdomains. Whenever a user is requesting a smart subdomain, it’s possible to get a different kind of information, for example, the country of the user so the request can be redirected to the nearest server of the country. They offer up to 1 million DNS requests per month.
