When a DNS server receives a request, it responds with the IP address for the requested domain.ĭNS was created in 1983, then it was improved in 1987. DNS work depends on a set of DNS servers that store information about domain names and the IP addresses assigned to their respective domain names. What DNS and DNSSEC isĭomain Name System is a hierarchical distributed system that provides information about domain names. DNS does have certain issues but the respective organizations are working hard to continuously improve it.īelow we’ll explain what DNSCrypt is and how it helps users, and we’ll provide instructions how to set it up.
One of the core parts of the Internet is the Domain Name System. All this has been made possible by a set of different technologies. It’s available now for the Mac, and Linux/Windows versions are forthcoming.No doubt Internet has dramatically changed the way people live and work. Sadly, it’s not a full proxy so it won’t hide your browsing habits from local censors. The system has automatic failover to an unsecured state and can prevent folks from snooping on your DNS calls in a coffee shop or unsecured cyber cafe. We know that claims alone don’t work in the security world, however, so we’ve opened up the source to our DNSCrypt code base and it’s available on GitHub (ed: not yet posted).ĭNSCrypt has the potential to be the most impactful advancement in Internet security since SSL, significantly improving every single Internet user’s online security and privacy. It doesn’t require any changes to domain names or how they work, it simply provides a method for securely encrypting communication between our customers and our DNS servers in our data centers. In the same way the SSL turns HTTP web traffic into HTTPS encrypted Web traffic, DNSCrypt turns regular DNS traffic into encrypted DNS traffic that is secure from eavesdropping and man-in-the-middle attacks. They've even made the source code available for free here so that independent security experts can test their claims. Considering most DNS sessions are plaintext, this a huge deal.
What does it do? Basically DNSCrypt wraps your DNS conversation in an SSL wrapper. The service also automatically enables OpenDNS on your machine, thereby killing multiple birds with one multi-megabyte OS extension. The service also prevents man-in-the-middle DNS attacks.
Now OpenDNS is offering DNSCrypt, a service that completely encrypts your DNS sessions, ensuring that evil ha><0rZ can't see where you're headed on the web. We’ve talked about OpenDNS quite a bit over the years, noting that these guys know what geeks like: free, fast DNS lookups that smooth out the Internet’s rough edges and shave seconds off of many web tasks.
