10 Benefits of Using a Third-Party/Custom DNS Service

By default, your computer uses the DNS server addresses set by your Internet Service Provider (ISP). You have no obligation to stay with your default DNS. There are various companies that provide DNS services with much better speed, privacy, and many security-related options. Following are some of the Benefits of using a third-party DNS service.

Benefits of using a Third-Party DNS Service

Speed Improvements

The alternative DNS servers are usually better in speed, and better in name resolution than the default Internet Service Provider (ISP) DNS servers. There are various tools that you can use to test the performance of these third-party ISPs against your local ISP.


The third-party DNS services provide many Privacy related guarantees that the ISPs don’t. Depending on the country and its laws, the ISP of a specific location may not be as privacy-centric as some of the third-party DNS service providers.

More Reliable

The DNS services provided by the major tech companies are more likely to give you better service than the ones by your local ISP. They have better infrastructure, and hence, there are fewer chances of a downtime in their DNS servers.


Many local ISPs try to inject ads into their networks. Such ISPs will not block these ad networks (and potential malware networks) as blocking them goes against their interests. You can prevent that by using an alternative DNS service.


The larger third-party DNS services are better at filtering and categorising websites, and blocking harmful or malicious websites.

Visit Censored Websites

The local ISP may be blocking the websites or the content that is censored in that region. Various DNS services let its users access the content that is blocked in their specific region.

Access Blocked Content

There are various online media services that are restricted to a country or a region. Only the visitors to the specific locations are allowed to access those services. Some third-party DNS services let you bypass this restriction.

Advanced Security Services

Big technology companies develop and implement the latest and the most advanced features in the DNS system. One such feature is DNSSEC, which enhance the web protection. You can use this feature with Cloudflare and Google Public DNS. The local ISP may not be able to provide you with such services.

Parental Controls

Parental Controls is a setting that you must use if you have young children at home. A DNS service provider called OpenDNS lets you create your own filtering rules. You can block access to adult, malicious, and other types of websites that are not suitable for children.

Specific Interests

Some DNS service providers have positioned themselves superior to others in specific areas. For example, the Comodo Secure DNS is focused on antivirus and computer security, the Cisco OpenDNS is focused on content filtering and customizable rules, and the Cloudflare is focused on pure speed. You can select a DNS service depending upon your specific interests and requirements.
