As with every service, you get what you pay for and it’s no different here. Free DNS can be good but it’s nothing compared to a Premium paid version. Granted, not everyone wants to pay and depending on their needs they might not need to, but paid DNS is always a better choice. Apart from the increased website performance and security, you also get additional features.
For instance, Dynamic DNS and Secondary DNS are a staple of the premium DNS service. The Dynamic DNS works with dynamic IP addresses and it allows users to access their home computer from anywhere in the world. The Secondary DNS works as a backup of sorts which is always a plus. This is just a small fraction of what a premium DNS can do and the exact number of features will depend on the service provider, which is one of the features we look for when testing a DNS service.
We also test DNS servers to see if it can filter content to block ads, trackers, malicious, phishing or family-unfriendly sites, depending on your needs.
