Q. What is DNS?
A. Domain Name System (DNS) is the translation of human friendly computer names (such as websites) to computer IP addresses in a way computers understand. Once armed with an IP address, your computer can communicate directly with it's intended destination.
Q. What is Recursive DNS?
A. Recursive DNS refers to the portion of the overall DNS system that, when asked for the IP address of a specific domain name, will get the answer. Sometimes, these recursive servers will have the answer cached in memory and respond immediately. Other times, the recursive server will have to start querying authoritative servers to get the answer. Comodo Secure DNS provides this FREE service to ensure you receive the answers on where to go in a quick, efficient, and safe manner.
Q. What is Authoritative DNS?
A. Authoritative DNS refers to the servers in the Domain Name System that are responsible for giving the "authoritative" IP address for the domain name you are asking for or telling you where else you should look for that answer. If you have experience registering domain names, the DNS servers you provide with a registration for a particular domain are "authoritative" for that domain.
Getting Started/ Configuration
Q. How do I set up my computer to use Comodo Secure DNS?
A. If you have a router, we recommend changing your setting there so that all the computers attached to that router will automatically be updated. However, if you would like to modify your computer instead, please follow the instructions for your particular operating system. Instructions can be found in the Switch Now section.
Q. Do I need to change my DNS settings in individual programs like my Web browser and/or email program?
A. No. Individual programs typically rely on the DNS settings of their operating systems.
Q. How do I stop using Comodo Secure DNS?
A. Comodo Secure DNS can be removed from your system by simply changing your DNS server settings back to their original settings.
Q. I typed in the DNS numbers you listed in my browser, but nothing showed up. What's wrong?
A. The IP addresses 184.108.40.206 and 220.127.116.11 are not configured to display a website. This is done for performance and security reasons.
Q. Who should use Comodo Secure DNS?
A. Comodo Secure DNS is for everyone -- especially those who are interested in a more reliable, faster, and safer Internet experience!
Q. How much does this cost?
A. Nothing. Comodo Secure DNS is a FREE service.
Q. Is there any software to install?
A. No. Comodo Secure DNS is the industry-leading recursive DNS service. To use this service, a small change must be made to your network settings for your operating system. This can be done at any time, does not require any software, and is easily reversed. To see how to configure your computer or network to use Comodo Secure DNS, use the tabs above to navigate to the Switch Now section.
Q. Can I manage my DNS records for my domain(s) through Comodo Secure DNS?
A. No. Comodo Secure DNS is a recursive DNS service. To manage your DNS records, you need an authoritative DNS service.
Q. Will your services interfere with any of the websites or other services I use?
A. There should be no interference reaching websites or services outside of your local network. Utilizing fully qualified Internet addresses on properly configured local networks will also result in the proper response while trying to reach local servers or services within your network. Please feel free to contact us to get further details if you have any issues reaching local servers or services within your network so we can assist you. Please note in an effort to provide a better user experience and to remain consistent with current Internet trends (i.e. Microsoft IE users, Google Toolbar customers, Registrars, ISPs, etc.) we do not return "NX Domain" responses for domains that do not exist, but rather Comodo Secure DNS search page similar to those returned by Microsoft Live or Google.
Q. How do I start using Comodo Secure DNS?
A. Simply change your DNS settings to use the Comodo Secure DNS servers:
