Comodo Secure DNS

Enjoy a safer, smarter and faster Internet

Comodo Secure DNS is a domain name resolution service that resolves your DNS requests through our worldwide network of redundant DNS servers. This can provide a much faster and more reliable Internet browsing experience than using the DNS servers provided by your ISP and does not require any hardware or software installation.

Comodo Secure DNS gives you a safer, smarter and faster Internet because it’s:

More Reliable - Comodo’s Secure DNS’s server infrastructure currently spans 15 locations (nodes) and five continents around the world. This allows us to offer you the most reliable fully redundant DNS service anywhere. Each node has multiple servers, and is connected by several Tier 1 carriers to the Internet.

Faster - Our strategically placed nodes are located at the most optimal intersections of the Internet. Unlike most DNS providers, our request routing technology means that no matter where you are located in the world, your DNS requests are answered by the closest available set of servers. Combine this with our huge cache and we can get the answers you seek faster and more reliably than ever before.

Smarter - Comodo’s highly structured DNS system and guide pages get you where you want to be, when you inadvertently attempt to go to a site that doesn’t exist. Parked’ or ‘not in use’ domains are automatically detected and forwarded.

Safer - As a leading provider of computer security solutions, we are keenly aware of the dangers that plague the Internet today. Our ‘name cache invalidation’ solution signals the Comodo Secure DNS recursive servers whenever a DNS record is updated, fundamentally eliminating the concept of a TTL. Directing your requests through our highly secure servers can also reduces your exposure to the DNS Cache Poisoning attacks that may affect everybody else using your ISP.
