Superior Performance with DNS Loadbalancing

The OX PowerDNS loadbalancer teases out the best possible performance of your DNS deployment. It optimizes DNS traffic in front of recursive DNS servers and delivers low latency to subscribers based on location, time and content. The OX PowerDNS Recursor loadbalancer is highly DNS-, DoS- and abuse-aware with built-in protection to filter and block malicious and abusive traffic. Provide your subscribers with globally optimized delivery while adding an additional layer of protection.

Malware Protection for Operators and Subscribers

An increase in malware attacks drives the need for additional security layers. OX PowerDNS comes with dynamic protection against subscriber originated issues, runaway traffic from high-bandwidth customers and denial-of-service (DoS) attacks. The platform analyses incoming DNS traffic for suspicious patterns and selectively blocks it if certain thresholds are broken. In this way, the resolvers are protected and will keep functioning during a DNS-based DoS attack. The underlying OX PowerDNS malware filtering is an open platform that integrates with all major malware threat list providers. In this way, PowerDNS provides protection for your subscribers from malware, phishing and malicious traffic and secures operators against DDoS and other attacks, while OX Protect provides you with a solution that lets end users protect their families.

The system provides numerous metrics that can be integrated with existing monitoring and alerting solutions, and can provide automated periodic reporting on the status of your DNS. Our Professional Services will help you implement integration into your existing systems. OX PowerDNS also comes with support for NFV and the capability to automate deployment and configuration of recursor instances on the network.

OX PowerDNS and 5G Networks

When the next generation of 5G mobile networks is deployed, mobile latencies are expected to drop significantly. In order to optimally benefit from those very low latencies, and to achieve the fastest responses at the service level, DNS recursion will need to be performed near the edge of your 5G networks, very close to the user. This comes with operational challenges for the network operators regarding deployment automation and orchestration of many (edge-based) DNS nodes. OX PowerDNS is 5G ready. This means it provides the necessary capabilities for deploying, configuring and orchestrating virtual instances on many edge-nodes in a network. It also provides a control-plane for managing the configuration of those DNS nodes. For more information on the requirements that 5G-networks pose on DNS please see here.
