Appendix 2 - Comodo Secure DNS Service
Introduction
Comodo Secure DNS service replaces your existing Recursive DNS Servers and resolves all your DNS requests exclusively through Comodo's proprietary directory services platform. Most of the networks use recursive DNS services that are provided by their ISP or that reside on their own set of small DNS servers but it becomes essential to have a secure and broadly distributed DNS service to have a faster and safe DNS resolution.

Background Note: Every device on the internet is uniquely identified by a 32-bit number (IPv4 address) or a 128-bit number (IPv6 address). While this is perfectly satisfactory for computers, humans are far more comfortable remembering names rather than a string of numbers. The 'Domain Name System' (DNS) provides the translation between those names and numbers. Virtually every piece of software, device, and service on the internet utilizes DNS to communicate with one another. DNS also makes this information available across the entire span of the internet, allowing users to find information remotely. |
Comodo Secure DNS is a broadly distributed recursive DNS service that gives you full control to determine how your clients interact with internet. It requires no hardware or software and provides reliable, faster, smarter and safer internet experience.
- Reliable - Comodo Secure DNS Directory Services Platform currently spans across 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, Comodo Secure DNS Directory Services Platform uses 'Anycast' routing technology - which means that no matter where you are located in the world, your DNS requests are answered by the closest available Comodo Secure DNS set of servers. Combine this with our huge cache and we can get the answers you seek faster and more reliably than anyone else. Furthermore, our "name cache invalidation" solution signals the Comodo Secure DNS recursive servers anytime one of our authoritative customers or partners updates a DNS record, fundamentally eliminating the concept of a TTL.

Smarter - Comodo's highly structured search and guide pages get you where you want to be, when you inadvertently attempt to go to a site that doesn't exist.
-
Safer - As a leading provider of computer security solutions, Comodo is keenly aware of the dangers that plague the internet today. Secure DNS helps users keep safe online with its malware domain filtering feature. Secure DNS references a real-time block list (RBL) of harmful websites (i.e. phishing sites, malware sites, spyware sites, excessive advertising sites, etc.) and will warn you whenever you attempt to access a site containing potentially threatening content. 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.
