More Reliable – Comodo Secure DNS’s server infrastructure currently spans 15 locations (nodes) and five continents around the world. This allows Comodo 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 – Comodo uses strategically placed nodes are located at the most optimal intersections of the Internet. Unlike most DNS providers, the Comodo 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, resulting in information becoming available 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, Comodo is keenly aware of the dangers that plague the Internet today. The ‘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 highly secure servers can also reduce your exposure to the DNS Cache Poisoning attacks that may affect everybody else using your ISP.
