OPENDNS is the name of this type of service. In addition to functioning as a domain name server, promising to help users browse the web faster and smarter, OPENDNS can also protect against malware sites, phishing websites, and many other dangers.
This is a rather “unusual” money-making website. Whenever customers use the company’s services and type in an incorrect domain name, the system’s error correction will first intervene. If this system fails to work, the server will automatically suggest a series of websites with similar domain names to what you just typed, along with advertisements. The parent company earns money through these advertisements.
This method was previously used by VeriSign in the past but was not very successful.
To attract customers, the company offers a DNS service that promises to be faster, safer, and smarter.
It is faster because the servers are equipped with large caches, which improve response and processing times for requests.
It is smarter due to the error correction system for mistyped domain names. For example, if you want to visit www.google.com but only type www.google.co, the error correction system will still recognize it and correct it for you.
Safety is one of the main attractions of this DNS. By referring to a secret database built by the company itself, many malware and phishing websites have been removed from circulation.
Setting up and using this service is quite straightforward. The IP addresses for OPENDNS are 208.67.222.222 and 208.67.220.220. You can replace the IP of the server with the default DNS address currently in use on your machine. When making the change, be sure to save the old information in case of failure or if you change your mind. After replacing it, visit the website http://welcome.opendns.com/ to check.
