Next Generation DNS

Domain Name System Overview

All communication starts with a query... 

 

DNS performs a simple, but critical, translation service, allowing users to lookup a domain instead of an IP address (think of it as the yellow pages for the Internet). The concept of DNS dates back to the ARPANET era and the technology hasn't changed for the past 4 decades. 

Although performing a simple lookup sounds easy, DNS is a core building block of the Internet and use of its technology is universal.  Going forward, DNS will continue to be a fundamental building block of the Internet due to the adoption of CDNs and the Cloud using dynamic IP addresses.

Re-Designing DNS for the Future

Since everyone and everything uses DNS to navigate the Internet, we've decided to optimize DNS servers to solve some of the common network security, filtering, and analytics challenges along with the basic DNS query resolutions. 

For example, when a query is sent to our DNS, we perform several checks on the IP or Domain in question. Depending on the configuration, we block or re-direct queries before the queries leave the network. 

 

In addition, since every device sends hundreds or thousands of DNS requests daily, we incorporate the use of big data and artificial intelligence into our solution. The future of integrating DNS data with new technologies is bright.

Traditional DNS + New Features

Traditional DNS servers perform a simple but vital lookup service for navigating the Internet. We've re-designed our DNS technologies to leverage the advantages that DNS currently offers. 

From a network prospective, DNS is uniquely positioned to provide network security at scale. It acts as a gateway between all network devices and the open Internet, and it sits outside the data path. This means it knows about all network communications, but it doesn't get overwhelmed by the payload of each packet.   

DNS already has a mechanism to filter content. When you try to visit a domain that no longer exists the DNS sends a NX error. Our solution expands these basic building blocks to allow for customized granular content filtering.

DNS is one of the few data sources for network analytics that is not impacted by the increased adoption of encryption technologies. As such, DNS can provide data analytics of all communications between devices and domains.
